.NET Framework Library Source Code now available

As I blogged about a couple of months ago, Microsoft will release the .Net Framework source code – but only for sneak peaking.

This is now a reality. Only a limited subset of the libraries, but more is to come in the future.

This is the list of what is currently available:

  • .NET Base Class Libraries (including System, System.CodeDom, System.Collections, System.ComponentModel, System.Diagnostics, System.Drawing, System.Globalization, System.IO, System.Net, System.Reflection, System.Runtime, System.Security, System.Text, System.Threading, etc).
  • ASP.NET (System.Web, System.Web.Extensions)
  • Windows Forms (System.Windows.Forms)
  • Windows Presentation Foundation (System.Windows)
  • ADO.NET and XML (System.Data and System.Xml)

To enable this feature, you need to setup Visual Studio 2008 – here is a guide.
