I think this goes back to the problem of CFC's not being able to be serialized and or passed around to web services on remote servers. You are passing an instance of a CFC into your web service which is a complex object and the C# code has somehow serialized it, but the CF web service doesn't know how to reconstitute it. You might have to rethink the inputs to your C# code to pass in simple data types or at least serializable ones. I don't know what the equivalent to a struct would be in C#, but it might be a good start. Probably not what you wanted to hear, but just my guess anyway.
