使用Coherence和Moq时的System.BadImageFormatException

Question

When using the following line in a moq unit test, I get a System.BadImageFormatException.

mockDataAccessLayer.Setup(dal => dal.ListItems(It.IsAny<List<IFilter>>()));

The exception:

System.BadImageFormatException : [C:\Users\ric\AppData\Local\Temp\q3a2acu1.brz\RJ.DAL.test\assembly\dl3\cb8fb82f\e33b012a_c5f6cc01\RJ.DAL.test.DLL] The signature is incorrect.
at RJ.DAL.test.DALLayerTest.DataAccessLayerTest()

The full unit test:

[Test]
public void DataAccessLayerTest()
{   
    var mockDataAccessLayer = new Mock<IDAL>();
    mockDataAccessLayer.Setup(dal => dal.ListItems(It.IsAny<List<IFilter>>()));
    var dataAccessLayer = mockDataAccessLayer.Object;
}

I am fairly sure the problem lies with the List of IFilters, as I use very similar code elsewhere without the It.IsAny which works fine. Any ideas?

As Hans mentioned, it was due to missing an assembly for the interface. Adding the dll containing the interface fixed the problem.
