Custom classes in labview

[atk_nut]

OK,

I've been given two dll's. One contains the .net methods that I wish to run, and the other contains the definitions for the custom classes that the methods return.

I can add the first dll (with the methods) to the .net assembly references, but not the second. I can call the method, and it looks like the datatypes are there, but when I actually run the method. I get a .net exception:

File or assembly name dllnumber1, or one of its dependencies, was not found. in Untitled 1

My c# expert says, no problem, all you have to do is declare dll#2 in your code.

OK, so how do I do it?
