Steps to Reproduce

Add this to the static Main

Console.WriteLine($"BEFORE:");
Console.WriteLine($"  NUNIT_AUTOEXIT = {Environment.GetEnvironmentVariable("NUNIT_AUTOEXIT")}");
Console.WriteLine($"  NUNIT_AUTOEXIT = {Environment.GetEnvironmentVariable("NUNIT_AUTOEXIT")}");
Environment.GetEnvironmentVariables();
Console.WriteLine($"AFTER:");
Console.WriteLine($"  NUNIT_AUTOEXIT = {Environment.GetEnvironmentVariable("NUNIT_AUTOEXIT")}");
Console.WriteLine($"  NUNIT_AUTOEXIT = {Environment.GetEnvironmentVariable("NUNIT_AUTOEXIT")}");

[15645:495793] BEFORE:
[15645:495793]   NUNIT_AUTOEXIT = true
[15645:495793]   NUNIT_AUTOEXIT = true
[15645:495793] AFTER:
[15645:495793]   NUNIT_AUTOEXIT =
[15645:495793]   NUNIT_AUTOEXIT =

I did notice that setting the envvars in the app set them permanently. So this has to come in from the outside - say mlaunch.
