Non working templates and deprecated information

[Enter feedback here]
the analyzer templates reffered in this article seem deprecated. i just installed the workloads created the template and get numerous errors:

Also while the project is .NET Standard and i get it needs some runable framework to run tests etc, during project setup i had to select a .NET Framework version and now i'm getting errors for .NET Core... like WTF dudes?
