I’m having trouble adopting our application to be used as a Rhino plugin. We are using RhinoCommon and C# to write a plugin for Rhino5 64bit. We reference the nuget package WindowsAPICodePack-Core 1.1.2 (with a small fix to work in 64bit) to show a TaskDialog with custom buttons - but it’s not working. Anyone had similar experiences? It’s working perfectly if started as NUnit test or as plugin for other CAD software.
