Everybody was waiting for some major announcemnt today and here it is, about which I have just blogged:
""It's like some beautiful dream...We are releasing the source code for .NET Framework base class libraries under the Microsoft Reference License, and the source code will be downloadable and viewable by anyone who accepts the license agreement.In addition, Microsoft will introduce a capability in Visual Studio 2008 to allow you to debug into the .NET Framework source code using Visual Studio. With this capability, when you are stepping through code, you will be able to step into the source code for the .NET base class libraries.This release will include the Base Class Libraries (BCL), Windows Forms, ASP.NET, System.Data, and WPF. BCL includes many of the basic classes in the framework including collections, string and text handling, IO,serialization, remoting, and others. We plan to include additional libraries into the set as time goes on."
More Details to follow.
And here's the UPDATE: The main thing from Scott Guthrie,
"One of the things my team has been working to enable has been the ability for .NET developers to download and browse the source code of the .NET Framework libraries, and to easily enable debugging support in them.
Today I'm excited to announce that we'll be providing this with the .NET 3.5 and VS 2008 release later this year.
We'll begin by offering the source code (with source file comments included) for the .NET Base Class Libraries (System, System.IO, System.Collections, System.Configuration, System.Threading, System.Net, System.Security, System.Runtime, System.Text, etc), ASP.NET (System.Web), Windows Forms (System.Windows.Forms), ADO.NET (System.Data), XML (System.Xml), and WPF (System.Windows). We'll then be adding more libraries in the months ahead (including WCF, Workflow, and LINQ). The source code will be released under the Microsoft Reference License (MS-RL).
You'll be able to download the .NET Framework source libraries via a standalone install (allowing you to use any text editor to browse it locally). We will also provide integrated debugging support of it within VS 2008............."
