How can I decompiling IL code of .net framework

I want to investigate IL code of most .net framework library classes. Is it possible? I am trying to decompiling some dll (e.g.: System.Treading), and I only see signature of the functions. Then I go to mscorlib.dll and see only manifest. There is a way to see the real code?

You can use .NET Reflector (commercial but very good):

https://www.red-gate.com/products/dotnet-development/reflector/

You can open a .net assembly with it (.exe or .dll).

So you can also directly browse .NET Framework assemblies by selecting the framework version.

Select view IL or other language such as C# or VB code and it is done.

There is also for example this free tool (slow, very slow):

If you want to study the implementation of .Net classes. I suggest you use the reference code provided by Microsoft.

The main advantage of using the reference code, is that you can see the comments and other elements that will not be added to IL (like #define).

To study the effect of certain C# constructs on the generated IL, I would suggest using SharpLib.
