Debug .Net Framework's source code only shows disassembly in Visual Studio 2010

Question

Hi!

I'm trying to debug .Net Framework's source code using Visual Studio 2010 Professional. I followed the steps described in Raj Kaimal's post but I must be doing something wrong since the only code I'm getting to see is the disassembly code:

As you can see in the image, the Go to Source Code and the Load Symbols options are disabled. Nevertheless, symbols are downloaded from Microsoft's server since I can see them inside the local cache directory.

The code I'm debugging goes as follow:

var wr = WebRequest.Create("http://www.google.com");
Console.WriteLine("Web request created");
var req = wr.GetRequestStream();
Console.Read();

When I hit F11 to step into the first line of code, a window pops us looking for the "WebRequst.cs" file inside "f:\dd\ndp\fx\src\Net\System\Net\WebRequest.cs" which does not exists on my machine.

What am I missing? Thanks a lot for your help.

EDIT: I posted the same question inside the official asp.net forum, I will let you know if they give some clues.

Answer 1

in project properties target .net framework 4.0. I had the same issue when I was compiling for .net 3.5.
