NUnit has a very rich and readable constraint set. Normally you don’t need to do anything. But, there are some cases where it would be nice to be able to tweak these constraints. You can always wrap them and extend them that way, but then you lose all the other good stuff, like chaining. What is not so well known is that you can extend the existing constraints, they are **designed** to be extendable! In this post I will show how you can do that easily.

Setting up Visual Studio Code

C# extension

Add the standard C# extension

Solution extension

Add the solution extension

This goes together with organizing your code with a parent folder, called solution root, and then having each C# project in a corresponding subfolder. Add these projects to your solution using the solution extension.

Debugger

The C# debugger comes with the standard C# extension

Set up the debugger as shown in this post

If debugger won’t start, and saying things like Omnisharp server not running, then run the command (from the command palette) Omniserver restart and then Generate assets for debug.
