How to view .NET source code in Visual studio?

Question

.NET

How to view the .NET source code in Visual studio so that you can walk through the methods and classes, right in the studio without a debugger.

Answer 1

Options/Debugging/General check "enable .net framework source stepping". The download of the PDB file with sources will start immediately. Just keep in mind that they weigh a lot, and you will need enough space on the hard.
PS: If you want to debug .net, then you need to do These settings .
If you just want to navigate through the source, that one is more complicated. For normal navigation, links in the metadata to the source are needed. This was done only for core2, but over time they promise to add it to all versions. Personally, I use the "navigation to source / decompile methodes" setting in the resharper, but as an option there is an extension for vs Ref12, in this case, when got to defition in the browser, a page opens at https://referencesource.microsoft.com with the source.

If you mean .net framework libraries, then no way. their source code is classified information. you can see only the metadata (which class contains which methods, fields, etc. and a description of what they do), select the desired class -> Go To Definition or you can use the Object Browser (there you can generally see what the namespace consists of).

Answer 3

Resharper to the rescue, it has a built-in decompiler for dll
