I just updated Inventor 2013 from Sp2 Update 3 to Sp2 Update 6. Now, I can no longer add a reference to the Inventor Object Library in Visual Studio Premium 2013. Any suggestions?
What Reference are you using. The reference you want to use is Autodesk.Inventor.Interop.dll. I can't remember the directory in 2013 but in 2014 and up its in the Inventor installation directory bin\Public Assemblies.
It's a standalone application. Interestingly enough, Visual Studio won’t let me make the reference to the COM object, but I can reference the Autodesk.Inventor.Interop.dll file. That’s odd. However, it works.
Some COM libraries will work with Visual Studio but the recommended way of adding references for COM objects is through an Interop if available. Otherwise Visual Studio will attempt to make an interop dll on the fly through reflection on the COM library. And for Inventor the supplied assembly is recommended since it's built to more accurately represent the API as intended.
