TypeLoad Exception

[ShaneCarr]

The scenario: We are having a problem mocking an interface which is public. It is in a signed assembly which is a dependency of our dev code (we don't directly own the assembly).

The interface has a number return values which are concrete types (on methods i am not directly using our testing) and they are public. If i remove personal the problem just moves down to the next class.

For example these methods
ICollection DirectorySearch(ViewBase view, string queryString);
and
FindPeopleResults FindPeople(WellKnownFolderName wellKnownFolderName, SearchFilter filter, ItemView view);

Everything is public (no internal visible to i believe should be required). I don't see any reason these shoudl be casuing this type of issue, i am not actually mocking these or using these properties in my code the exception happens on the ".object" to generate the mock.

GetConversationScreenResponse getConversationScreenResponse = this.NewGetConversationScreenCommand(serviceMock.Object, flowFolderMock.Object).Execute(flowConversationId);

We also aren't mocking any of these methods that are causing the problem. it seems to be triggered by reflection in moq scanning the object and throwing an exception. I included the call stack below and the call stack from the test case. I spent a while on this any suggestions would be greatly appreciated!

Here is some sample code that seems to be causing the problem.

public class Persona : Item

...

[Attachable, ServiceObjectDefinition("Item")]
public class Item : ServiceObject

Plz try to repro with plain DynamicProxy or NSubstitute / FakeItEasy. If it
reproes (In almost sure if will), it's a Castle issue, not a Moq issue, I'm
afraid

Thanks again for the response. I figured out this problem, it had nothing to do with castle or MOQ. Posting the resolution as other people will likely face similar issue and this investigation may help.

The problem was we had a custom build assembly that didn't match assembly which was getting loaded from the gac before my suite ever ran, but we had built against the custom built assembly. The lesson is to break on exceptions and look at the loaded modules to double check that you have the right assemblies loaded then look at the il. This was tricky because this assembly was being loaded by vs and we have a custom built version improperly versioned which I didn't know about.
