Question: but i saw session Developing Windows Store Apps with HTML5 : Answer: Yes, we did a series on using HTML5. Great courses and worth checking out. But this series is focused on

C#

09:06:28 PDT

Question: Anyone do game dev for Win 8? Looking to stick with C# Answer: I'm doing some game dev in Windows 8, but I'm using a game engine (Scirra Construct2)

09:13:19 PDT

Question: What's the code to redeem again? Answer: You can download all the slides from the FAQ tab, the redeem code, links, and everything else will be in

09:18:27 PDT

Question: LOVED the C# JumPDTart. I'm watching this because of that experience. Respect for Jerry Nixon and

Daren May. Answer: They're favorites here in the studio too!

09:21:02 PDT

Question: Are there keyboard shortcuts for the various charms and gestures? Answer: Yes. Win + C brings up the Charms bar. Win + H is for share. Win + Q is for search. Win + W searches for

computer settings. Win + F searches for files. Win + K brings up devices. Win + I brings up the settings.

09:23:53 PDT

Question: Is share between running applications running in a same machine like old IPC (Inter Process

Communication)? Answer: Not exactly, though the use case is the same. A share is a data package that carries various types of data

from one app to any other app that the user has installed and chooses (the user is in control)

09:26:03 PDT

Question: Jeremy... Can you please recomend some XAML introductory courses for C#/VB.NET software

Question: I think they still should of kept the Start button on the desktop. Answer: I've heard that from a few others, but I don't miss it personally.

09:26:31 PDT

Question: I understand introducing a new gesture is costly affair, but is it possible programmatically to introduce new

gesture? How do we do it? Answer: Yes, creating new gestures is technically possible for sure. You can easily capture standard gestures, but

you can also capture pointer (touch, mouse, pen) input at the "manipulation" level which gives you the developer ultimate power.

09:26:47 PDT

Question: that jerry nixon is awesome Answer: So much agree!

09:26:55 PDT

Question: Is it possible to share information to host Windows Apps in Azure? any idea Answer: Can you rephrase the question? I don't understand.

09:28:29 PDT

Question: Is there a Windows 8, C++ jump start planned in the near future? Answer: I am thinking about a C++/DirectX course focused on gaming. Anybody interested?

09:29:52 PDT

Question: I have similar question to Rambhopal - Is it possible to share information between windows azure app and

windows 8 app? I guess it is possible. Answer: You can definitely leverage azure from you Windows 8 and Windows Phone 8 apps. Windows Azure Mobile

Services (WAMS) provides an extremely easy way to build backend data, authentication, and push notification services for your apps.

09:29:53 PDT

Question: Azure dashboard? I am not aware of it. Jeremy would you please share it? Answer: By dashboard, I'm referring to the management console. manage.windowsazure.com

09:30:55 PDT

Question: Pls share URL if you know about hosting windows apps in Windows Azure servers Answer: You don't host Windows apps in Azure. You host compute processes, websites, data, web services, etc.

09:31:49 PDT

Question: Iam a beginner at all this , do you think it will be useful for me ? Answer: This will be very useful, but potentially a bit fast-paced. I strongly recommend you join MVA and watch

09:35:42 PDT

Question: I am about to release my first Metro app. Was thinking of porting it to Windows Phone 8 also. Is the Api's

for Windows Metro app and Windows phone 8 apps similar or quite different Answer: There are many similarities but also many differences. The ease of porting will depend on the architecture

of your app. The design will certainly be different, but if you have a good engine behind your app, it will likely port very easily.

they go away.

09:36:49 PDT

Question: Is it possible to use skydrive as a stream? (E.g.: Listen music whic is stored on skydrive?) Answer: Yes, lookup Live Connect for connecting to SkyDrive from your Windows 8 app.

09:37:30 PDT

Question: Win Apps Hosting in Windows Azure and use SQL Azure DB Answer: You can host the SQL DB in Azure. The Windows App runs on the client (not in Azure)

09:38:18 PDT

Question: Saw the HTML/CSS Jump start. @codefoster and @palermo4 have a good chemistry. Was very

informative Answer: Thanks so much for the feedback! We love having @codefoster and @palermo4 in the MSL

09:39:57 PDT

Man, these guys are all over it!

09:39:57 PDT

Question: Why use the word "Toast" for notifications? Answer: Like toast pops up from your toaster... toast notifications pop up on the screen. It's weird, but that's what

they call them.

09:40:57 PDT

Question: I really should buy a Windows tablet. It seems like the only to fully beta test your application before

releasing it to the store. Answer: Yeah, you need to test your app on an ARM device before you start selling it. If you don't want to buy a

device though, you can go to a Windows App Lab and test on our hardware.

09:41:43 PDT

Question: can you please answer this one-for developing the apps in windows store, do i need to have a touch

enabled laptop to develop and test the environment? Answer: Nope. You can simulate touch in the Simulator. You do need Windows 8 and VS2012 (or the free Express

version).

09:42:11 PDT

Question: windows app lab what is that? any links? Answer: Windows Store App Labs https://applabs.msregistration.com/

09:42:29 PDT

Question: Can you post a link for the Windows App Lab? Answer: Windows Store App Labs https://applabs.msregistration.com/

09:43:18 PDT

Question: I would be interested, Frank. Would that be straight C++/DirectX or would it involve any third part game

engines? Answer: Hey Mike... Great question. My thinking is it would start out with a two mods of "gaming strategy" then focus

on C++/DirectX exclusively. Of course, it would be great to fold in a few other third-party apps (Unity/Mono, etc.) if there was time.

09:43:31 PDT

Question: could i try in a VS 2012 express edition? how about VS 2010 ULTIMATE is this also possible? Answer: Nope. Can't create Windows 8 apps in any version of VS2010.

09:43:54 PDT

Question: guess what calendar pushed a toast notification for this event for me Answer: I bet it wasn't Google Calendar!!

09:44:10 PDT

Question: @codefoster and @palermo4 and very funny to! Answer: +1

09:44:50 PDT

Question: roaming is like a profile roaming from DC? Answer: Sort of. Roaming doesn't roam your entire user profile necessarily. It allows app developers to roam

whatever data they choose. Users can still turn off roaming, however, so keep that in mind, devs.

09:47:01 PDT

Question: What's the most affordable way for a newly independent developer to obtain a Windows 8 license? Answer: Are you talking about a Windows Store Developer account?

09:47:02 PDT

Question: Is simulator enough for us to test?When I developped apps on iPhone,some bug just only exist on real

device Answer: Right, you should still test on a real device. Although, the Simulator is really just a remote desktop

connection (RDP) back to the localhost machine, so it's pretty solid.

09:48:22 PDT

Question: One of the requirements for getting your Metro app certified is that it should support Snapped mode.

Suppose the type of application that i am developing is such that it does not make sense to have a snapped mode. What should be the best way to handle such a scenario ? Just display a friendly message in snapped mode or there is something else i can do which will be more user friendly ? Answer: Exactly. See how the Store works in snapped mode. It doesn't. It just shows the Store logo. I would provide

a button that jumps the app out of snapped view and back to full screen, however. That's a good user experience.

09:48:50 PDT

Question: I would have chosen pop-tart notifications. Answer: Ditto

09:49:40 PDT

Question: yikes - doesn't appfabric host clients via RSS or sockets? Answer: I don't know. Bret, can you answer that?

09:50:15 PDT

Question: the desktop application i made in VS 2010 ult is it ok to migrate to vs 2012 express for windows 8? Answer: It is okay to migrate it. If you're asking if the migration is an automated process then the answer is 'no'.

09:53:53 PDT

Question: Thanks. Providing a button sounds like a good idea Answer: Windows.UI.ViewManagement.ApplicationView.TryUnsnap();

09:54:20 PDT

Question: By migration plan I mean kind of upgrade wizard which we see when we load a older VS project in new

VS version. Answer: Not that I know of.

09:54:28 PDT

Question: can windows 8 apps be created on "vs2012 for windows desktop" Answer: No

09:57:47 PDT

Question: i can't use VS Express for win8 JavaScript Apps? Answer: You can. You can use VS Express 2012 to make either XAML/C# or HTML/JavaScript apps.

09:58:10 PDT

Question: what is the font used in windows 8 applications Answer: Segoe (pronounced SEE-go)

10:00:30 PDT

Question: Are these sessions being recorded by any chance? Answer: Yes.

10:01:17 PDT

Question: Can't we use any other fonts except Segoe ? Answer: You can. You can use any font you want. Segoe is just the default font and it's recommended that you use it

unless you have good reason (branding, etc.) to use another font.

10:02:47 PDT

Question: Can windows 8 apps talk to custom peripherals like let's say a usb toaster ? Answer: Sure. You can access devices on the system and that includes devices plugged in through USB. I'll stick to

my 110V toaster however

10:03:21 PDT

Question: Can I use obfuscation with Windows 8 Apps to protect my code from reverse engineering ? Answer: Yes you can. There is not an obfuscation solution built into our framework. You need to get that from a 3rd

party.

10:04:11 PDT

Question: is it necessary that I should use xaml as a part for designing my application can I use various other tools

like devexpress tools in order to make my application entirely look like windows 8 app.. Answer: I am not sure I understand, but you can plug in various controls and components to avoid having to write

them yourself, and many already exist that follow the Windows 8 design principles so they "look like Windows 8"


Q&A Log


10:04:11 PDT

Question: can i make a desktop app (database) for win8 could it be used for win7? Answer: Desktop apps can run both on Win7 and Win8.

10:04:42 PDT

Question: What music do you guys play during the breaks? Answer: If you have a Windows Phone, use the Bing music search when you hear a track you like... or use Shazaam

on the other mobile platforms.

10:04:58 PDT

Question: is it necessary that I should use xaml as a part for designing my application can I use various other tools

like devexpress tools in order to make my application entirely look like windows 8 app.. Answer: You can use 3rd party XAML components from a variety of companies.

10:05:08 PDT

Question: What was the URL they gave for the design recommendations? Answer: I didn't see what they shared, but you can go to design.windows.com to see all of our documentation on

design for Windows 8.

10:07:05 PDT

Question: do any of the apps I can learn to make here work on android / iphone? or only windows phone? what

about a tablet other than windows 8 tablet Answer: When you write using XAML/C#, you're primarily targeting Windows 8 and Windows Phone 8, but there are

tricks to run C# on Android and iOS (Mono). If you want to write in HTML/JS, you can be a bit more cross-platform. There are JumPDTart videos on the HTML/JS track.

10:07:05 PDT

Question: ha ha Dennis, I couldn't guess what would you do with toaster plugged in with USB?

Answer: 2 days later, your toast is ready

10:07:10 PDT

Question: when can we download these great recordings? Answer: We will have them up on the MVA site early next week.

10:09:18 PDT

10:14:18 PDT

Question: do any of the apps I can learn to make here work on android / iphone? or only windows phone? what

about a tablet other than windows 8 tablet Daniel N. Egan replied publicly: Every platform is different, Jave for Android, Objective C for Ios,, C# for Windows..

Although YOu can use things like phone gap to go across many platforms. (But this session is about C# and Xaml)

10:14:27 PDT

Question: I have heard that we cant use native tools of windows phone and windows 8 using Html,css and JS but

through C# it is possible!, IS it true? Answer: You cannot make native Windows Phone apps using HTML/JS, but you can make native Windows 8 apps

using HTML/JS (see the JumPDTart series on the subject)

10:14:27 PDT

Question: can i join now? Answer: We're on a short break right now.

10:18:57 PDT

Question: Hi I just joined the session.. Is this video stream paused ? Answer: No. You may just be buffering.

10:20:14 PDT

Question: what does mc:Ingnorable stand for? Answer: http://msdn.microsoft.com/en-us/library/aa350024.aspx

10:21:56 PDT

Question: what does mc:Ingnorable stand for? Answer: mc is the prefix for the "markup-compatability" namespace. The mc:Ignorable="d" attribute is basically

telling the runtime XAML parser that it can ignore anything that starts with the "d:" prefix. Which, if you look up the "d:" prefix is the expression blend design namespace. Long story short, it tells the runtime to ignore anything in the markup that is intended for use by the design tools (Expression Blend or Visual Studio).

10:23:00 PDT

Question: Any links for the projects they are working on now ? Answer: http://xaml.codeplex.com

10:26:02 PDT

Question: a weird question, shoot me if you like, would JSON be ever used to achieve what we achieve using

XAML? a weird thought crossed my mind. Answer: No. JSON and XAML serve different purposes. XAML is a UI language, but JSON is a data format. XAML

doesn't represent data, it represents a hierarchy of UI elements.

Q&A Log


10:29:09 PDT

Question: jeremy, so are you saying that xaml is for the UI elements only? Answer: Yes. Generically, XAML is just a markup language that instantiates objects, but it's used almost entirely for

instantiating UI elements.

10:30:55 PDT

Question: But isn't XAML used for WF which is definition of control flow? Answer: Well, that's true. You've got me there. It's used "mostly" for UI, but WF is a good example of another use.

10:31:14 PDT

Question: and we have to give elements ids to use them in c# code? Answer: Yes. You need a way to refer to the XAML elements

10:31:25 PDT

Question: is XAML specific to .Net only? Answer: Yes. XAML is specific to .NET

10:31:33 PDT

Question:

> Quoted question: I guess that leads to a question ... not that I have ever tried this but apparently WPF is not a deployable Win8 project type? Adam Tuliper replied privately: Answer: That is correct (from a project type standpoint), it would be a Windows Store C# app type rather than a

Windows WPF app type.

10:32:17 PDT

Question: Do we use only the XAML to build all UI design for our apps, any other choices? Answer: You can avoid XAML altogether if you want to imperatively create all of your UI elements using C#. Or you

can write an app using HTML/JavaScript. In that case, HTML takes the place of XAML as your UI language.

10:32:47 PDT

Question: What is the best way to sync data between WP8 and W8 apps when I need only sync initial and final state

? Answer: Windows Azure Mobile Services is the best way. WAMS has SDKs for both Windows 8 and Windows

Phone 8 and also for iOS, Android, and HTML!

10:33:48 PDT

Question: Odd that Visual Studio 2012 on Windows 8 provides a WPF project type then Answer: You can create a WPF app that runs on Windows 8, but it's not a Windows Store app. It's a desktop app.

Everything you could make for Windows 7 can still be created for Windows 8.

10:34:00 PDT

Question: Can we have the use xaml processor engine in our app? like IE hosted in windows form. Answer: I don't know.

10:36:51 PDT

Question: do we have good app demo for windows azure app for windows 8 or windows phone 8 Answer: sima, there is an excellent tutorial for using Windows Azure Mobile Services with Windows 8, Windows

Phone 8, and even iOS and Android here: http://www.windowsazure.com/en-us/develop/mobile/

10:37:23 PDT

Question: um... is that something new in 2012 XAML - does not represent data? Attributes vs Properties? Answer: No, that's been the nature of XAML all along.... representing objects more than data.

10:38:14 PDT

Question: is it also a .exe extension file for install in a win8 Answer: No. Windows 8 apps are "packages" that incorporate a lot of modern app concepts and security measures.

10:39:14 PDT

Question: how much does it cost to use WAMS? or is it free? Answer: It's free right now while it's in preview, but it will cost when it's live. It's not expensive, though since it's based

on a simple website instance.

10:40:01 PDT

Question: Is there any way to map between XAML and HTML?Like button in HTML and Button in XAML? Answer: Do you mean in an app? You could, but I don't know why you would and it would be a manual process.

10:40:02 PDT

Question: > Quoted question: jeremy, so are you saying that xaml is for the UI elements only? > Quoted answer: Yes. Generically, XAML is just a markup language that instantiates objects, but it's used almost

entirely for instantiating UI elements. Answer: I'll add a little more clarification. XAML is a way of "declaring" objects and their relationships. They don't

actually get "instantiated" until the "InitializeComponent()" method is called in the page's constructor. The "InitializeComponent()" method is actually generated by the compiler. It walks the XAML, and creates instances for each of the declared objects at runtime.

10:42:24 PDT

Question: Wanna understand doesn't JSON represent object structure to some extent? I do understand JSON does

nt have meta as XML has it... Answer: It may represent the data of an object, yes.

10:42:36 PDT

Question: > Quoted question: and we have to give elements ids to use them in c# code? > Quoted answer: Yes. You need a way to refer to the XAML elements Answer: You can actually reference objects declared in XAML even if they don't have a "Name". You can do that by

walking that XAML "tree". The page has a "Content" property from which you can grab the root object, and then use appropriate methods from there to get to its contents. For example: Button theButton = (((Grid)this.Content).Children[1]) as Button;

10:43:39 PDT

Question: ok thanks. what should we use in a VS2010 express for desktop to make a win8 app? (e.g. windows forms

app or wpf?) coz i dont any choices in my VS2010 EXPRESS FOR DESKTOP Answer: You can't make Windows 8 apps in VS2010. You must have Windows 8 and VS2012 (either the Express

version or a higher version)

10:44:05 PDT

Question: sorry, i mean jerry and daren are using VS2012 express for desktop? or for web? Answer: They are actually using VS2012 Ultimate.

10:45:21 PDT

Question: Out of curiosity, who's the little figurine on the table between our two presenters? Answer: Not sure, but I think we should make some good guesses. Looks like a Beatle to me.

10:46:55 PDT

Question: can you change the xaml element properties during run-time from c# code? hide/display or such Answer: Definitely. You can reference by their name in code, and simply assign new property values.

10:46:56 PDT

Question: can CSS be used inside XAML? Answer: Siva, XAML doesn't support CSS, but rather has its own hierarchical style system called "Resource

Dictionaries". These provide a very rich way to not only provide common styles, but complete templates for controls.

10:49:46 PDT

Question: can CSS be used inside XAML? Answer: Nope. CSS is for HTML only.

10:49:47 PDT

Question: is the implementation of XAML parser completely inhouse to MS? or does it use any of the standards

parser like W3C? Answer: The XAML parser is proprietary to Microsoft.

10:50:14 PDT

Question: Do style have cascading property like css? Answer: XAML uses "Resource Dictionaries" for styling and templating rather than CSS.

10:51:03 PDT

Question: Sorry if this has already been asked: Will this presentation be available on demand in the near future? Answer: It sure will.

Question: as a starter in win8 app, what should i use in vs2012 express for desktop windows form app or wpf. or

should i use vs2012 express for web Answer: Mar Vil, to create Windows Store apps for Windows 8 you need either "Visual Studio 2012 Express for

Windows 8" or a full version of "Visual Studio 2012" (Pro or Ultimate)

10:52:28 PDT

Question: Between CSS and Resource Dictionaries, what is more complicated? The same question for XAML and

HTML5? Answer: They both have their strengths. If you are a .NET developer, you will likely find it easier to get started with

C#/XAML apps, or if you are coming from a web development background, HTML5/JS may be a better choice.

10:52:36 PDT

Question: lately its bufferring a lot so again what is the UserControl good for?? Answer: A UserControl is good for encapsulating some UI (and some associated functionality) so that it can be

reused. If you need to create something that itself contains a number of UI elements (some text fields and a button perhaps), but you know that you'll have it in a few different places in your app, then you should create it as a UserControl.

10:53:01 PDT

Question: @Bret: I am using Premium, can I create too? Answer: Tho, yes, as long as it Visual Studio 2012

10:53:25 PDT

Question: How to target multiple screen sizes using C# for windows store app ? Answer: You do that by using VisualStates. You have VisualStates for snapped view, filled view, full view, portrait,

etc. and you can specify different XAML within each of the different ViewStates.

10:53:48 PDT

Question: do you a link for vs2012 for win8? Answer: Go to http://dev.windows.com and choose "download"

10:54:12 PDT

Question:

> Quoted answer: I am thinking about a C++/DirectX course focused on gaming. Anybody interested? Hi Frank, interest from Sunny Hertfordshire for this, a foundational course focusing on 3D graphics, with a followup course later on game specifics would be ideal for me. Possibly a C++/DirectX course for Obj-C/OpenGL coders would be good. Answer: Thanks a ton for the feedback, mrpaulb!

10:55:53 PDT

Question: Is VS 2012 still the XAML parser with the code behind pages? Answer: Not sure of the question. The XAML parser is accessible to you through the

System.Windows.Application.LoadComponent method. (http://msdn.microsoft.com/en-us/library/system.windows.application.loadcomponent.aspx) . This is actually the method used by your application at runtime to initialize all of the objects declared in your XAML file.

10:57:01 PDT

Question: Will it be steep learning curve to go from VS 2010 to 2012? Answer: VS 2012 and VS 2010 are not significantly different from a general use perspective. You should be able to

pick it right up.

10:57:13 PDT

Question: Will it be steep learning curve to go from VS 2010 to 2012? Answer: No. The design looks different (cooler IMHO) but all of the existing apps you made with VS2010 work much

the same. The new Windows Store apps are the big new thing.

10:57:31 PDT

Question: How can I decide which page will be shown when program is ran? Answer: The package.appxmanifest points to a .xaml file

10:57:57 PDT

Question: How can I decide which page will be shown when program is ran? Answer: The initial page displayed is determined by the code in the App.xaml.cs code file's OnLaunched method.

You can modify the code in that method to load a different page at startup.

10:59:10 PDT

Question: Does WinRT provide a Data Picker control? Answer: Did you mean to say a DatePicker control? It doesn't, but the Calipso (sp?) controls provide it.

11:01:37 PDT

Question: I mean Date / time picker Answer: Those are available in Callisto (http://timheuer.com/blog/archive/2012/05/31/introducing-callisto-a-xaml-

toolkit-for-metro-apps.aspx)

11:03:49 PDT

Question: ok , thanks .. will have a look at Calipso Answer: See my correction. I meant Callisto (http://timheuer.com/blog/archive/2012/05/31/introducing-callisto-a-

xaml-toolkit-for-metro-apps.aspx)

11:05:46 PDT

Question: Does Blend come with VS2012 or we must install it separatedly? Answer: It comes with it. In fact, it comes with the Express version even which is free. So you never have to pay for

Blend.

11:07:51 PDT

Question: IE metro version didn't work for me, am in 64 bit Windows 8. Silverlight latest version installed. Answer: Silverlight doesn't work in the IE Windows Store app. It does work in the desktop version.

11:22:12 PDT

Question: Jeremy is a great teacher, he is doing his best to teach me game dev!

Answer: Sharing... Would be great tweet listing @codefoster and #MSJumPDTart!

11:22:16 PDT

Question: Hi Jeremy and everyone. Answer: Hello, maifs!

11:23:03 PDT

Question: agreed the impression of wide screen content is the killer in win 8 Answer: Yes!

11:23:19 PDT

Question: any way to save the layout in vs 2012 express or ultimate for windows 8? I have to change the vertical

orientation to horizontal one every time I am making an app. Answer: Are you referring to saving your VS workspace (the position and visibility of panes, etc.)?

11:27:59 PDT

Question: how do i get a developer license Answer: A developer license is granted for free by launching Visual Studio. You only need to provide a Microsoft

Account (Live ID). It expires in a month, but renews easily and automatically as well.

http://www.pluralsight.com/


Q&A Log


11:28:48 PDT

Question: how do we offload between GPU and CPU? Answer: XAML is automatically hardware accelerated, so you don't even need to worry about it.

11:29:44 PDT

Question: Can't we do that using single piece of code ? Using % instead of px ? Answer: Repeat your question with full context please.

11:32:07 PDT

Question: yes, the vs workspace. Answer: It's not built into VS. I wish. Look for an Extension (in VS go to the Tools menu to Extensions and Updates)

and look for one.

11:38:50 PDT

Question: To target multiple devices. Can't we do that using single piece of code ? Using % instead of px ? Answer: Using percentages is one way, but that doesn't always work. The various layout techniques in XAML

attempt to account for a huge variety of desired behaviors.

11:39:58 PDT

Question: Jeremy - Any idea why the developer license is good for only one month? Although easy to renew, kind of

hassle with no apparent reason for the hassle. Answer: The reason is to be sure that the user continuously has the right to run Windows Store apps that he didn't

get from the Store. If it didn't check often then a person could get away with running an app for a long time without license to do so.

11:40:33 PDT

Question: XAMLShow code has some incompleteness. Answer: You should follow up with Jerry (http://www.jerrynixon.com)

11:40:51 PDT

Question: how do I find out if it is using GPU or CPU? any perf counters? Answer: I don't know of a way to get stats on that.

11:41:23 PDT

Question: stackPanel works as float@css? Answer: Yes, but I hope you know that there's a better way to float in CSS now - flexboxes. You can see an example

in my codeSHOW app (http://aka.ms/codeshowapp)

http://www.jerrynixon.com/

Q&A Log


11:42:23 PDT

Question: can't we get the updated XAMLShow code? I am seeing that there is no new updates at codeplex. Answer: I don't know why the updates are not there. You'll have to follow up with Jerry or keep checking the

xaml.codeplex.com link.

11:43:00 PDT

Question: which layout is more lighter on processor? i.e. with lot of controls which of the layout is easy on the CPU Answer: Do you mean between the various XAML layout methods or between XAML and HTML/CSS?

11:43:45 PDT

Question: Are there any open sources and commercial XAML games? Sorry, for my ignorance I am not aware as we

speak.. Answer: I'm not aware of any.

11:46:12 PDT

Question: between the various XAML layout methods Answer: I don't know. Sorry.

11:46:12 PDT

Question: [thumsUp] yes i see your codeShow session, Great session! Answer: Thanks. If ya feel like it, rate the codeSHOW app in the Store to get the ratings up. Appreciate it.

11:47:13 PDT

Question: when i use animations/transformations shoud i use a canvas for GPU performance? Answer: Not necessarily. All of the layout components are hardware accelerated... not just the canvas element.

11:50:17 PDT

Question: Okay Jeremy between different layout options in HTML which one is more quicker, i.e. tables, div floating

and flexboxes etc. Answer: Again, there's no difference. All of the declared HTML elements and their CSS styles, transformations, and

animations are hardware accelerated.

11:53:24 PDT

Question: how to correct designer load error in vs2012 Answer: Do you get any errors in your XAML or C# files in code view? Can you build your project?

11:54:45 PDT

Question: Ok, so canvas is usefull to hide overflow elements and svg! or i am wrong? Answer: Canvas cannot show SVG. There's not a way to show SVG in XAML unfortunately. Canvas is just like a

more generic version of the Grid. It doesn't have the columns and rows, so it's just absolute layout.

11:55:20 PDT

Question: the project builds Answer: I'm afraid I can't help. There could be so many reasons the designer cannot load.

11:55:45 PDT

Question: can i use svg out a canvas? Answer: No, there's no simple way to show SVG in XAML.

12:07:23 PDT

Question: What are the cool extensions that you guys use in your VS? Answer: It looks like they're using ReSharper

12:14:09 PDT

developers Answer: Isn't this a two day jumPDTart with just XAML?

important polls later!

12:25:39 PDT

Question: Jerry & Frank - funny guys!

Answer: Thanks for the feedback my good man! Glad you appreciate my attempts at humor!

12:29:50 PDT

Question: Has Microsoft finally buried VB.NET? No single jump start series thus far under this much hyped and

trumpeted windows store application developments and windows 8 platform. So sad for many of us from VB.NET platform. Answer: Every single concept that you learn in C# is directly transferrable and I think VB devs are accustomed to

translating on the fly, so a VB course may be a bit too much repeat. All of the concept would be the same and it would only be syntactical differences.

Question: I'm from Brazil. In the XAML code design and code of business are in different files? Answer: Hey Jose - so XAML is focused on the presentation (and, ideally, the code-behind performs presentation

based processing), your business logic is normally encapsulated in view models (MVVM) and services.
