With Visual Studio, I can debug my .NET Core applications running in Windows and WSL 2. For WSL 2, I use this extension. This is working fine. I can also debug my unit tests in Windows. This is working fine too. However, I do not know how how to debug my unit tests with Visual Studio running in WSL 2. I hope someone can help me and explain how I can debug not just my console apps and web apps in WSL 2, but also my unit tests. Please let me know.

Update 2022 Feb - VS 2022
Run on a win 10 dev machine
dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart
dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart
Reboot!
Run on the dev machine
wsl --set-default-version 2
wsl --install -d Ubuntu
Run in your new wsl machine
wget https://packages.microsoft.com/config/ubuntu/20.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
sudo apt update && sudo apt upgrade -y
sudo apt install apt-transport-https git
sudo apt update && sudo apt install dotnet-sdk-6.0 -y
Add testenvironments.json to your solution root
{
"version": "1",
"environments": [
{
"name": "Ubuntu",
"type": "wsl",
"wslDistribution": "Ubuntu"
}
]
}
Visual Studio will show a new dropdown in the test explorer, select "Ubuntu" and run or debugg your tests.
This setup does not depend on Docker. Winver shows "20h2"

Debugging tests isn't supported using ".NET Core Debugging with WSL 2" extension.
This tooling does not support running tests in WSL2, but I do know our sister team has this on their backlog to enable! .NET Core Debugging with WSL 2 - Q&A
Update: The feature is available from within Visual Studio 2022. It enables you to debug tests both in WSL 2 and Docker.
A howto is available here: https://docs.microsoft.com/en-us/visualstudio/test/remote-testing?view=vs-2022
