SecAnnotate can be used to analyze your assemblies, especially APTCA assemblies in order to find transparency violations without needing code coverage from a test case.  The static analysis provided by SecAnnotate is valuable in ensuring that your assembly is fully correct from a transparency perspective.  You can get the tool now in beta form here, and read an in-depth article on the .NET Security Blog about how this tool might be used for a simple APTCA library.
