C#: Finding a Missing Dependency

Question

I'm getting this error message whiile running a Webservice I'm working on. it builds, but this happens when I Invoke:

File or assembly name (Redacted).Framework, or one of its dependencies, was not found

The stack trace shows that between my code and the target of the exception, there are 3 referenced DLLs and 4 layers of System.Reflection. How do I find what was passed into the method that threw the Exception, or at least find what dependency it's looking for and where it's looking for it?

I do not have access to the code nor symbols for the referenced DLLs that lie between my code and the Exception.

Answer 1

You can also look at the exception and/or inner exception of it.

You can remote debug the process to see exception details. If it is a dll, you can add a sleep or better, wait until a debugger is present : "System.Diagnostics.Debugger.IsAttached" and then Attach to it and wait the exception. If the error is at start then fusion is probably the only way.

Fusion is also very nice.

Answer 2

DependencyWalker helps in finding out which DLLs are missing.

Answer 3

You may be able to use the Assembly Binding Log Viewer:
