Issue

1. Install Qt VS Tools in VS 2019 (16.2.1) for the first time.
2. Create a new Project > Qt Console Application
3. Fill in the project details under "Configure your new project"
4. Click "Create"

This produces a cryptic and unhelpful error message, "Object reference not set to an instance of an object."

Solution

Go to Extensions > Qt VS Tools > Qt Options, and add a valid Qt Version.

After that, repeating the steps above will allow the project configuration to proceed normally.

Suggestion

Rather than the cryptic message, show a more informative message like "No Qt versions have been configured in Visual Studio yet. Go to Extensions > Qt VS Tools > Qt Options to add a version."
