I am going through the C# API tutorial right now, and I am having issues with the Cosworks and CWaddinCallback references not being found when I compile. As you can see from my image, on the right at least the Cosworks dll file is referenced, (I'm not sure which file the CWaddinCallback dll is) but when I compile it errors.
I followed the directions here: cosmosworks object not defined
But it didn't work. In fact, I don't think that any of my references seem to be working, as I add in different assemblies, I seem to get the same namespace error.
I also repaired my SW installation from the installation manager.
Please let me know any suggestions.
