I am using the latest Moq (4.2.1502.911) in Visual Studio 2013 to mock an internal interface contained in another project. Both projects are signed with the same key. After searching here and elsewhere on the web I figured I had to add InternalsVisibleTo for the test assembly and "DynamicProxyGenAssembly2", using Moq's public key like so:
[assembly: InternalsVisibleTo("UnitTestProject1, PublicKey=00240000048000009...
[assembly: InternalsVisibleTo("DynamicProxyGenAssembly2, PublicKey=002400000...
Now when I run my test method I still get the following error:
Test Name: TestMethod1
Test FullName: UnitTestProject1.Class1Test.TestMethod1
Test Source: c:\Users\******\Documents\Visual Studio 2013\Projects\MoqTest\UnitTestProject1\UnitTest1.cs : line 13
Test Outcome: Failed
Test Duration: 0:00:00,0693592
Result Message:
Test method UnitTestProject1.Class1Test.TestMethod1 threw exception:

Is there something else to do to get this to work? Here is a minimal compilable example: https://www.dropbox.com/s/c2slwq4do5ttp9p/MoqTest.zip?dl=0
Using the following Public Key value solved the issue for me:
0024000004800000940000000602000000240000525341310004000001000100c547cac37abd99c8db225ef2f6c8a3602f3b3606cc9891605d02baa56104f4cfc0734aa39b93bf7852f7d9266654753cc297e7d2edfe0bac1cdcf9f717241550e0a7b191195b7667bb4f64bcb8e2121380fd1d9d46ad2d92d2d15605093924cceaf74c4861eff62abf69b9291ed0a340e113be11e6a7d3113e92484cf7045cc7
I initially tried to get the public key using sn.exe but I think the public key it returns is for Moq rather than DynamicProxyGenAssembly2. I got the above key from the Moq GitHub page:
https://github.com/Moq/moq4/wiki/Quickstart
// This assembly is the default dynamic assembly generated Castle DynamicProxy,
// used by Moq. Paste in a single line.
[assembly:InternalsVisibleTo("DynamicProxyGenAssembly2,PublicKey=0024000004800000940000000602000000240000525341310004000001000100c547cac37abd99c8db225ef2f6c8a3602f3b3606cc9891605d02baa56104f4cfc0734aa39b93bf7852f7d9266654753cc297e7d2edfe0bac1cdcf9f717241550e0a7b191195b7667bb4f64bcb8e2121380fd1d9d46ad2d92d2d15605093924cceaf74c4861eff62abf69b9291ed0a340e113be11e6a7d3113e92484cf7045cc7")]
