It could be any number of things. Likely causes are:

• The assembly cannot be found
• An assembly that your assembly depends upon cannot be found
• The assembly is found but the type isn't in it
• The type's static constructor throws an exception

Your best bet is to use the Fusion log viewer to help diagnose it. Documentation is here:

(FYI "Fusion" was the code name of the team that designed the assembly loading system; it is somewhat unfortunate that the code name ended up in the file name of the shipped product. The thing should have been called "AssemblyBindingLogViewer.exe" or some such thing.)

Answer 2

In my case problem was that I had two projects that used the same libraries in one solution. I've updated DLLs only in first project. So when I built solution, second project its override DLLs from first project(project build order).

Example:

Solution:

--MainProject

------MyDll v5.3.2.0

--Prototype

------MyDll v5.0.0.0

Problem gone after update DLLs in second project.
