.NET SDK code hangs at AdminToken()

I have adapted boilerplate code from the Box SDK documentation using the .NET SDK that is able to successfully connect and upload files using the Dev Token authentication.  However, when I attempt to authenticate using the JWT method, my code just hangs at the AdminToken() call.  It never throws an error or times out.  The code just sits waiting for a response that never arrives.  As shown below, I can reach a breakpoint at the first line, but a breakpoint at the second line is never reached.

 

     var adminToken = boxJWT.AdminToken(); 

     var client = boxJWT.AdminClient(adminToken);

 

I'm not sure how to troubleshoot this issue at this point and any guidance would be greatly appreciated.

  Was this problem ever resolved, or was it just ignored?

  This is may be related to a known Box issue (https://github.com/box/box-windows-sdk-v2/issues/638).   I was able to determine the AdminToken() method was hanging when invoked on the main thread of a WebAPI Controller.  I was able to successful bypass the issue by spawning a new thread to execute the logic that ultimately invokes the AdminToken() method.

   is correct.

  You can get this to work if you create the AdminToken in a thread other than your controller thread. 

  This is what worked for me:

   

   

  BoxClient _boxClient = null;
  var thread = new System.Threading.Thread(() =>
  {
     var boxJWT = new BoxJWTAuth(boxConfig); // create boxConfig elsewhere
     var adminToken = boxJWT.AdminToken(); // create adminToken in new thread
     _boxClient = boxJWT.AdminClient(adminToken); // set your _boxClient
  });
  thread.Start(); // start the thread
  thread.Join(); // wait for the thread to finish (ugly code).
  Debug.Assert(_boxClient != null); // success!

   

   

  This is discussed in depth here:

  Hey Everyone, 

   

  We are aware of the issue with getting Admin Tokens using the .NET SDK. We have a PR that is working its way through the process. Once that PR lands successfully we will cut a new release of the SDK. Our ETA for this is early next week. 

  
  Thanks,

  John Townsend
