To All:

I have a wrapper class DLL that I wrote in C#, It wraps another DLL and communicates with a Delphi 6 EXE. All is well on my development box but when we deploy this to an app server I get a message that 'Class is not registered'. I suspect that the C# DLL could be the culprit, mainly because I'm not sure if I need to register it in any way or where on the app server I need to put it. Therefore, I wouldn't be surprised that the Delphi EXE cannot find it. Currently I have tried putting it in the same folder as the Delphi EXE but no luck.

In general, where do you put a .NET DLL when deployed? Should it be registered with Regsvr or Gacutil? Do I need just the DLL or also the 'Interop' piece?

Thanks,
