   That came in with the new package updates. We really need to get our xUnit tests running automatically, as I rushed #662 through to unblock another developer.

   The root cause is that .NET enabled a safety check that is completely valid, and we were previously skirting it in these tests. The test setup function that initializes the AssemblyLoadContext should only be called once, but is being for each test it seems.

   Sorry, I haven't even had time to get this filed to get fixed properly. Thanks for reporting.

   Andy Jordan (@andschwa) I use below code to fix calling once issue, but I meet another issue when fix it.

   public static object setupObject;
   
           // Initialize the Core PowerShell AssemblyLoadContext
           public RunspaceTests()
           {
               if(setupObject==null)
               {
                   setupObject=new object();
                   PowerShellAssemblyLoadContextInitializer.SetPowerShellAssemblyLoadContext(AppContext.BaseDirectory);
               }
           }

   Can you re-test on the latest master branch? I know I saw the same errors in the last few days, but I can't reproduce it any more.

   Strange. It only reproduces intermittently. 1/3 runs just now.

   That's no problem, it reproed for me eventually, just not the first or second time. Which is strange. I'll look into this further.
