Wie Scott Guthrie auf seinem Blog berichtet, steht nun endlich der source code des .NET Frameworks zur Verfügung.

Bisher beinhaltet er folgende Teile des .NET Frameworks:

• .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)

Es wird außerdem bereits an der Veröffentlichung weiterer Teile, wie zum Beispiel WCF, WF oder LINQ gearbeitet.

Wie man den source code zum Debuggen in Visual Studio 2008 einbindet findet man ebenfalls auf Guthrie's Blog.

Der source code unterliegt dabei folgender Lizenz:

Reference License

"The .NET Framework source is being released under a read-only reference license. When we announced that we were releasing the source back in October, some people had concerns about the potential impact of their viewing the source. To help clarify and address these concerns, we made a small change to the license to specifically call out that the license does not apply to users developing software for a non-Windows platform that has “the same or substantially the same features or functionality” as the .NET Framework. If the software you are developing is for Windows platforms, you can look at the code, even if that software has "the same or substantially the same features or functionality" as the .NET Framework."
