C# trying to use async Task request to POST to rest API - task never run

Dear all,

I am trying to send files to a server using an async await Task paradigm, but it appears that when C# attempts to execute this task the task is never completed.

I've tried to pull the async part of the code out of the main event loop,  using a well-known design pattern, where all async code is in its own library, and when I call the async code, I do something like this:

main loop

   doSomeAsyncStuff().Wait()

end main loop

This pattern is often used when running async code in console apps, for example where async code cannot be executed.  

So I'm not sure why this is not working.  Is there something within Grasshopper which will not allow sync Tasks to run?  I'd assume that others have hit API's inside of Grasshopper before using C#.  How can I work around this issue?

For what it is worth, I am using the NuGet package RestSharp.

Many thanks!
