In your WSL terminal or in VS Code using terminal of your ubuntu distro, run below command to edit the ~/.profile file.

sudo vim ~/.profile

At the end of the file content add your environment variables in following syntax.

export MYAPP_CONFIG_PATH="/mnt/c/myconfig/my-config.json"

export MYAPP_EnvName="Demo"

Then save the file with ESC+:wq!  (wrting to file with vim).

If you want check if the update to file is saved, you can run cat ~/.profile

Once you have the  ~/.profile updated with your envronement variable your .NET core applications can access them while running in your Ubuntu WSL2 distro.
