Before you add UI Tools controls, add references to the UI Tools assemblies in a Visual Studio project.
When adding references, include the following required DLL references:
- Autodesk.ETO.UI.dll (UI Tools assemblies)
- Autodesk.ETO.UI.Intent.dll (UI Tools assemblies)
- Autodesk.Intent.API.dll (core)
- Autodesk.IntentBase.dll (assemblies)
- Autodesk.Inventor.Interop.dll (UI runs as an Inventor Addin)
