Go to Definition of class only showing public members

Question

When I right click on a class (that is part of an third party assembly - not code I have written) in Visual Studio and select \"Go to Definition\", I can see all the methods

Answer 1

You can find the answer on the doc page:

When you try to run the Go To Definition or Peek Definition command for types or members that are marked as internal, Visual Studio does not display their metadata as source code, regardless of whether the referencing assembly is a friend or not.

If you want to see the source code of the assembly, you have two options:

• Use a decompile tool like e.g. ILSpy.
• In Visual Studio 2017 version 15.6+, you can set an option to see decompiled source code when you view the definition of a type. This feature can be enabled in the Tools > Options > Text Editor > C# > Advanced section.
