2. (Can't Add View from Controller in VS 2015 : "There was an error running the selected code generator")

Answer 1

The issue is now fixed with the latest release of Visual Studio 2019: version 16.2.5: https://docs.microsoft.com/en-us/visualstudio/releases/2019/release-notes#16.2.5

The issue would only to happen when:

• you have the web.config file for your project open in Visual Studio.

So the workaround for was:

• if you have the error, make sure you close the web.config file and you will be able to scaffold controllers.
