Answer 2

For me the solution was to change the version in global.json to reflect the installed one.

Like the others said the version can be found running dotnet --info in cmd

This:

{
  "projects": [ "src", "test" ],
  "sdk": {
    "version": "2.0.3"
  }
}

Became:

{
  "projects": [ "src", "test" ],
  "sdk": {
    "version": "2.1.4"
  }
}

You can also create the global.json file by running

dotnet new globaljson --sdk-version 2.1.4

at root of project
