Downhi l l B ik es Tour the Current Si te

Overview of Part 04

Welcome to the Visual Studio .NET Guided Tour. This tour will cover the three

key areas of the .NET developer experience: client applications, server

applications, and XML Web services.

Today, the computing industry is converging on a new model for building

software, enabling an integrated world of software applications for businesses

and individuals. This model enables a standard way of connecting software

applications and exchanging information using the Internet. This new,

Internet-based integration methodology, called XML Web services, enables

applications, machines, and business processes to work together in waysnever previously possible.

In this tour, youll see how a fictional bicycle manufacturer takes advantage

of XML Web services to improve customer service and operations. Well go

through the steps as Downhill Bikes quickly adds functionality to its Web site

to collect customer feedback. Next well add new capabilities so that

customers can check on the status of their orders and management can view

real-time Web page hits.

Lets start off by walking through the Downhill Bikes Web site as it stands

today, by browsing the catalog, placing items in the shopping cart, and then

placing an order. The Guided Tour will then step us through the addition of

new client, server, and services features, using Visual Studio .NET.

Bui ld an XML Web Serv ice

Overview of Part 14

In this part, well build our first XML Web service in Visual Studio .NET. The

Web service will demonstrate one of the key benefits of using XML Web

services: Integration of disparate data sources into an easy to use data

object. Well unite two different data sources, XML and SQL Server, into a

single ADO.NET object called a DataSet. The DataSet serializes automatically

as XML, and is returned by the XML Web service.

XML Web services form the core business logic in the .NET application model.

In an upcoming section, well write a Microsoft Visual Basic .NET program

based on Microsoft Windows that will use this Web service. Then, wellcreate Web and mobile interfaces as well. In each case, the logic in the XML

Web service will serve as the core of the application, running separately fromwhatever presentation model we choose as appropriate for the situation.

After finishing the Guided Tour, youll have a good understanding of the

importance and power of XML Web services, and how Microsoft Visual Studio

.NET enables developers to quickly and easily build Web services, and

incorporate them into business applications.

Bui ld ing a Rich Windows Form

Overview of Part 24

Windows Forms is Microsofts next generation rich client forms package that

breaks through the ceiling in desktop applications that once existed.

Delivered as part of the .NET Framework, Windows Forms is available to all

Visual Studio .NET developers, enabling developers to use the skills they

possess today and the languages they know now to build the most powerful

desktop applications ever.

So, back to our sample company, Downhill Bikes. The company wants to add a

smart client so that their call center staff can quickly retrieve details of

customer orders as they field customer inquiries.

Were going to build a Windows Forms-based application using the Visual

Studio .NET designer. Using a third-party control, we will then extend the

form to add reporting, and we will call the XML Web service we built in Part

1. Youll see how easy it is to build and extend Windows Forms with Visual

Studio .NET, and how straightforward it is to integrate business data and logic

residing in XML Web services.

Bui ld ing a Web Form and Test for Scal abi l i t y

Overview of Part 44

With Visual Studio .NET and Web Forms, developers can rapidly develop Web

applications that run in any browser on any operating system using the same

techniques previously used to build form-based desktop applications.

Application Center Test (ACT), a new feature integrated with Visual Studio

.NET Enterprise Architect, enables developers to gather performance metrics

and perform functional testing of XML Web services within the Visual Studio

.NET development environment.

Before Downhill Bikes goes live wi th their new application, they would like to

know that it will scale well. Using a built-in tool like Application Center Test,their developers and testers can see the immediate effects of the changes

they make in the performance of their application.

In this part, we will build a Web Form that accesses the previously built Web

service. Then we will load test the Web service with ACT.

3Step 6 of 6: Add Page Output Caching4

While the page is under load, well turn on page caching, with just one line of

code. The increase in the number of pages served per second should jumpdramatically. Notice that ASP.NET does not require us to stop or disrupt the

Web site when we update a page. We just save the page and the changes takeeffect immediately.

a. Click the orders test item in the left pane.

b. From the Actions menu, click Start Test. CTRL+F5

c. Once the test has started, click Show Details.

d. While the load test is running, switch back to Visual Studio .NET.

e. From the View menu, click Solution Explorer. CTRL+ALT+L

f. Double-click the Orders.aspx file.

g. From the View menu, click HTML Source. CTRL+PgDn

h. Place the insertion point at the beginning of the second line:

47/72

43

i. Double-click the 4.6 Output Cache code snippet.

j. From the File menu, click Save All. CTRL+SHIFT+S

k. Switch back to the Test Status window. Click the Show Details >> button to see

the graph.

You should see a jump in the number of Requests per Second (RPS) being served

up by the page. Since the page is cached (for 10 seconds at a time), were

drastically reducing the number of database calls.

l. Close the Application Center Test windows.

m. In Visual Studio .NET, from the Window menu, click Close All Documents. If it

asks to save changes, click Yes.

Summary

Part 4 of the Guided Tour enabled us to build an ASP.NET Web application and testit using Application Center Test (ACT). The Web Form-based application we built

was constructed using the same development paradigms previously used to build

form-based desktop applications effectively leveling the learning curve to Web

application development. We then employed ACT to load test our Web application

to ensure scalability in a production environment.

In Part 5, well integrate the functionality of third-party XML Web services into our

Web application.

XML Web Services at Work

Overview of Part 54

XML Web services will revolutionize software development both inside and

outside the firewall. Visual Studio .NET makes it easy to create and consume

Web services, using the familiar metaphor of the application component.

Developers using Visual Studio .NET can simply right-click in the Solution

Explorer window and select Add Web Reference. From there, they need

only supply the URL to the Web service on their intranet or the Web, or

browse the UDDI (Universal Description, Discovery, and Integration) registry

to locate desirable Web references. The Web service is then available for use

from within Visual Studio, with statement completion and other IntelliSensefeatures automatically supported.

When Downhill Bikes wants to implement a new service for customers, the

company needs tools to help their developers turn ideas into implementation.

By using Visual Studio .NET, developers can add new functionality in a matter

of hours, not days.

In this part of the tour, youll add a Web reference to a third-party Microsoft

partner to the Web application. The new functionality will enable Downhill

Bikes to offer gift certificates to its customers. You will then add a Web

reference to a service provided by one of DownhillBikes partners so

customers can find authorized bike stores to redeem their certificates.

Overview of Part 64

The Microsoft Mobile Internet Toolkit (MMIT), available as an add-on to Visual

Studio .NET, provides the tools to enable mobile Web application

development. MMIT makes it easy to build a single mobile Web-based

application that will automatically generate HTML, compact HTML (cHTML),

or Wireless Markup Language (WML), depending on the target device's

capabilities, and do so using business logic in XML Web services. Now with

MMIT, targeting multiple devices with a single Visual Studio .NET application

is as seamless as building a rich Windows-based desktop application.

Having added new gift certificate capabilities to its site in the previous part,Downhill Bikes now needs an easy way for their dealers to validate the gift

certificates online. They also want an easy way for their customers to checkthe balance of their gift certificates online.

In this part you will use the Mobile Web designer in Visual Studio .NET to build

a Web page that can be accessed by a variety of devices, giving

DownhillBikes dealers and their customers complete flexibility in running the

mobile Web application.

PART 6: B UILD A WEB PAGE MOBIL E

3Step 7 of 7: Summary4

The Visual Studio .NET Guided Tour covered three areas: building client

application, web-based server applications, and XML Web Services.

The Microsoft .NET platform pivots itself around these 3 fundamentals that

are driving the digital revolution. First, the platform was built in concert withthe Microsoft strategy around XML Web services the crucial factor in solving

the pressing problem of software and business integration. Second, Microsoft.NET provides the underlying substrate to deliver client experiences tailored

to the desktop PC, the thin-client Web browser, and to the multitude ofemerging smart devices. Finally, the Microsoft .NET platform recognizes the

need for enterprise-critical server software and integration.

Visual Studio .NET represents the cornerstone to the Microsoft .NET platform.

It is the tool that developers will use to drive their organizations and theircustomers into the world of XML Web services. Like the .NET platform itself,

Visual Studio .NET aligns itself around the essentials of his digital revolution XML Web services, Clients, and Servers.

By providing the most efficient way to both build and consume XML Webservices, Visual Studio .NET keeps developers on the vanguard of next

generation application development. In addition, Visual Studio .NET extendsthe concept of RAD to every facet of the client experience, enabling

developers to build desktop, Web, and mobile applications using the skillsthey already have and the languages they already know. Finally, Visual Studio

.NET demystifies server-side development providing RAD development ofbusiness logic, supplying the tools needed to deploy data-rich Internet

applications, and delivering the premier suite of enterprise servers to satisfy

every business need.

With Visual Studio .NET, the once unattainable goals of developers and

organizations alike are finally brought within reach. Empowering

organizations to seamlessly move to the world of XML Web services,

delivering resources for every client experience, and addressing the issues ofserver development and integration Visual Studio .NET unleashes the power

of .NET.

Summary

The final part to the Guided Tour provided an introduction to the Microsoft Mobile

Internet Toolkit (MMIT). MMIT provided a forms-based visual interface to build

mobile applications for a variety of emerging smart mobile devices.
