Problem with Unit Testing Revit 2012 addin in Visual Studio 2010

[RevitApprentice]

I am trying to create unit test in VS2010 for Revit addin that I developed. Problem is when I create unit test for a method and then run that test, I get this message:

Test method TestProject1.SimpleTestCommandTest.ExecuteTest threw exception: System.IO.FileNotFoundException: Could not load file or assembly 'RevitAPIUI.dll' or one of its dependencies. The specified module could not be found.

RevitAPIUI.dll is properly added to references of Revit addin project, and also in references of test project.

Any idea what should I do to fix this?

I ran into a similar issue a while ago when I was trying to use reflection to list some of Revit's enums.

I didn't really need to get this working so I eventually gave up, but before I did I added a handler for the AssemblyResolve event to try to find the issue.  It turns out that the issue was caused by the Revit assemblies' dependency on the Visual C++ Runtime.

It seems the solution is to ensure the VC++ Runtime is loaded into the process in order to satisfy Revit's dependencies, simply referencing the VC++ assemblies won't help you as the runtime needs to be loaded a specific way.  I had other time constraints so I gave up after this and I didn't look into how to load the runtime properly.

I hope this helps.

Hi, Matt. Thank you for your answer. I'll try doing what you suggested. Hopefully, it will give results.
