Hi,
I'm new to assembly.. I just literally copied paste the source code here https://docs.microsoft.com/en-us/powerapps/developer/common-data-service/tutorial-write-plug-in#create-a-plug-in-project
and followed step by step just to see how assembly works
But I keep getting this error after several attempts of fixing it, no luck
