Revit API[Csharp] addin error cannot run when installing pyRevit: Set property 'System.Windows.ResourceDictionary.DeferrableContent' threw an exception.

[Anonymous]

Hello everyone, hope you can help me!

Normally if I don't have pyRevit installed => My add-in works OKay.

But when i install pyRevit =>  run my add-in again it gives the following error: Set property 'System.Windows.ResourceDictionary.DeferrableContent' threw an exception.

Thanks everyone!!!

I would suggest checking whether this behaviour has already been discussed in the pyRevit repository. If not, you might want to raise an issue for it there.
