In many situations I need the full name of a class, to use it to run commands in PMC like specifying the
string fullyQualifiedName = typeof(MyType).AssemblyQualifiedName;
A quick search of the Visual Studio Extensions Gallery has lead me this extension: Copy Qualified Name for Visual Studio which appears to possibly do what you are after.
Once installed, right click on a class name and select
Copy qualified name option from the context, and the qualified name of the class will be copied to the clipboard.
