Creating solutions and projects in VS code

This script will create a new solution called MySolution, two folders called src and tests, a console app called MyProject in the src folder, and a test project called MyProjectTests in the tests folder. Change the names to suit. In VS Code, CTRL+F2 will allow you to edit all of the instances of a selected word at the same time.
If you want C# projects, omit the '-lang F#' from both project lines, change the file extensions to '.csproj' from '.fsproj', and remove the lines that add the FsUnit and FsUnit.XUnit NuGet packages.
Select all of the script text.
To run the script in the Terminal, you can do either of the following:

• Choose the Terminal menu item and then select 'Run Selected Text'.

• Press CTRL+SHIFT+P to open the Command Palette and then type 'TRSTAT'. Select the 'Terminal: Run Selected Text in Active Terminal' item.

The script will now execute in the Terminal.
You can delete the file with the script in if you want as you no longer need it.

Summary

It's slightly more complicated than doing this in Visual Studio or Rider but once you have the scripts, it's easy to reuse them. I highly recommend getting to know VS Code better.
