Hello,
I am brand new to playing with the ArcGIS Pro SDK. Stepping out from the world of writing python toolboxes and wanting to build addins in Pro.
I have installed Visual Studio 2019 Community version and I am running ArcGIS Pro 2.7.1. So I believe I have version 4.8 of the .NET Framework.
Does anyone know why I would be getting this message in VS when I complete the following steps:


Thanks
