What is .Net Core?• Open source development platform maintained by Microsoft and .Net

Community on Github. (https://github.com/dotnet/core)

• Cross-platform; supporting Windows, macOS and Linux

• Compatible with .NET Framework, Xamarin and Mono, via the .NET Standard Library

• The C# and F# (VB is coming) can be used to write apps and libraries

• Flexible deployment with Docker support.

Mono vs .Net Core• .Net Core is not based on Mono.

• Mono supports a subset of the .NET Framework app-models (for example WinForms), .NET Core doesn’t support.

• Mono supports large subset .NET Framework APIs using same assemblies. .NET Core needs own compiled version.

• Mono is focused on mobile platforms in recent years, .NET Core is focused on cloud.

ASP.NET Core

.Net Core

ASP.NET Core• No longer based on System.Web.dll. It is based on a set of granular and

well factored NuGet packages.

• Simply a console app that creates a web server in its Main method.

• Includes a managed cross-platform web server, called Kestrel, that you would typically run behind a production web server like IIS or nginx

• Doesn’t yet have some critical modules, such as WebSocket and SignalR
