I have tried creating some commands with Visual Studio 2005 in C#. Converting ellipsejig to VS2005, compiles fine. However I get the error Unknown command "ELLIPSEJIG" when I type in the command after using netload to load the debug compile of the assembly. I get the same error with a hand keyed sample for Hello world. The VB samples provided convert, complile and run just fine. Do I need anohter version of Visual Studo for C# to run? I am using AtuoCAD 2008.
