You are using Visual Studio 2008 (SP1 or not -- doesn't matter).
You have test project that is signed with strong key and that strong key has a password on it.
You are trying to create a unit test for private method and are trying to create accessor.
You have an error like that:
"Creation of the private accessor for Xyz failed"
You have that error because you excluded "Test References" folder and YourProject.accessor file from your test project.
The reason why you excluded YourProject.accessor file from your project is that you were getting a compilation error:
"Unable to obtain public key for StrongNameKeyPair".
The reason why you are getting that error is that VS 2008 SP1 and even VS 2010 Beta 1 have a bug.
Workaround for that bug is to turn off strong key signing on your test project.
