Warnings in VS2017 but all fine with VS2015

Question

When load my .NET Frameowrk 4.6.2 solution in Visual Studio 2017, it gives me the following warning:

Severity Code Description Project File Line Suppression Stat         


        

Answer 1

Are you sure, you installed all needed packages for your project? It could be a not installed feature. Go in the launcher to modify and check, are there all dependencies installed?

Answer 2

I had this show up as an error when building shortly after migrating a solution from vs2015 to 2017, and then also doing some git restructuring. As it turns out, I think git was actually the culprit.

Regardless, manually deleting the bin & obj folders in the affected projects solved it for me. (Clean alone wasn't cutting it.)
