FileNotFoundException - File or assembly name.. or.. dependencies.. not found

[id]

Hi,

I was wondering if someone can shed some insight into this problem i'm
having. I am decent with C++ but very new to managed C++.

I have a managed c++ class library which wraps some unmanaged c++ code. At
the moment i'm using a test harness which is a C++.NET Windows Forms
Application project. (I have also tried writing the Test harness in VB.NET
and C# but got the same error).

What happens is that when i start up the test harness, the form loads, but
when i click the button to run the function i am testing from the class
library, i get the error i have pasted below.

I have tried explicitly defining the path of the class library's output
directory using the Reference Path project property, and have also tried
copying the project output manually into the test harness' executable dir.
ANd now i'm not sure what else to try!

Thanks in advance for any help/info..

its dependencies, was not found.
