Q:

Visual Studio 2015 RC Pex creates tests for public methods only

I was under the impression that once I have the entry below in my assemblyinfo.cs file 
[assembly: InternalsVisibleTo("MyAssembliesName")]
, then pex should be able to see all internal methods in my class definition, in addition to the public methods. So, when does Pex not creat unit tests for the internal methods in my class? 

A:

The RC version does not yet support exploring non-publicly accessible methods. However, we are addressing this in the next upcoming release. Thank you for your interest in IntelliTest!
