I have a problem on vs to adding a new view:
Scaffolding failed. Could not load information for project
C:\Users\PC\source\repos\CoreDemo\BusinessLayer\BusinessLayer.csproj
To see more information, enable tracing by setting environment variable 'codegen_trace' = 1.
I have same problem, I couldn't find any solution. If you have more than one project try to unload them except web project. You can add a view. When you add your view, you can load them. It works with this way. It should be a bug.
Also, you can check this topic:
Could not load information for project X after update codegeneration 6.0.9
