I don’t really mind to launch Revit myself or set it as an external app in VS to save the extra click. I’m working with a large model. Even if I simplify it into a smaller test model, very likely to miss some of details. Forcing me to that routine above, close, modify code, build and waiting model kicks in…
I don’t know if there’s any tools like Add-in Manager in Revit SDK, avoid exiting Revit every build.
