Browsing the .NET Framework source code from Visual Studio

Question

I know that I can set up Visual Studio to debug through the .NET framework source code.

But is there a way that I can browse the code while NOT debugging - i.e., bei

Answer 1

There is the .NET Mass Downloader, but I think the straightforward answer to your question is, no.

However I now see Microsoft has made the code more easily downloadable.

Nevertheless note that even for your own code, when not debugging, unless you have the project open, VS does not help you locate source code (even though when you find it yourself break points will work when you start debugging again, if the .pdb files correspond).

Answer 2

With ReSharper it's possible to browse .NET sources by enabling ReSharper -> Options -> Tools -> External Sources -> Navigation to Sources. After enabling this option new menu item "Navigate To -> Decompiled Sources" appears by right click on type/method/whatever. Navigation also works with F12 for me.

Answer 3

I've never tried this but supposedly the code is publicly available:

Answer 4

I just discovered this extension that pretty much addresses my problem. The only thing is that it opens the source in the browser rather than in Visual Studio, but it's no big deal because even in the browser you can click the source code to navigate to types etc.

It was presented on Scott Hanselman's blog a couple of days ago:

Community member and fabulous coder Schabse Laks has created a Visual Studio extension for VS2010, 2012, and 2013! This extension sends calls to Go To Definition (or pressing F12 on a symbol) directly to the code online (when it's .NET Framework code, not yours).

You can download this companion "Ref12" Visual Studio Extension now! Just Goto Definition on any .NET type we have source for and it'll launch your default browser so you can explore the .NET Framework source yourself! Thanks Schabse!

Answer 5

I am using Visual Studio 2013 Ultimate.

1. Choose menu: TOOLS \ Extensions and Updates...

2. Choose Visual Studio Gallery \ Search Results. Search term: Ref12.

3. Download then install.

4. Restart Visual Studio.

5. Try: Click mouse on Class or method, press F12 and see result at http://referencesource.microsoft.com/

Answer 6

I downloaded the .NET Framework source code from here http://referencesource.microsoft.com/netframework.aspx.

Since I am working with .NET 4.0, I chose ".Net/4" from the list. (What is ".NET/8.0" in that list? No idea.)

I wrote some scripts to rearrange the bloody mess they give us:

• Into a reasonable hierarchy of directories;
• To remove duplicated code (why is every file doubled, or was my install bad?);
• Rename all top-level namespaces to not conflict with native ones baked into Intellisense.
• Example: System.Windows.Controls -> xSystem.Windows.Controls

Then follow these steps:

1. Create a new Visual Studio project of type "Class Library"
2. Remove all references -- yes, even the system ones.
3. Drag/drop all of your massaged .NET code into the root of your project.
4. Wait about 30 minutes for VS processing. VS will appear to freeze; be patient.

Intellisense/ReSharper still complains about heaps of problems, but now I can right click and select "Go to Declaration/Implementation".

Visual Studio is about 600MB with this project loaded.
