httpclient.GetAsync issue when using UWP

[ccarlo88]

Hello!

First, congrats for the .NET API for Matrix! It worked really well with the Console example and is nice to have a SDK developed in .NET. I was making some testes with the sdk and when using UWP it hangs out here:

public MatrixRequestError Get (string apiPath, bool authenticate, out JToken result)
{
apiPath = GetPath (apiPath,authenticate);
Task task = client.GetAsync(apiPath); //Here more exactly
var res = RequestWrap(task);
res.Wait();
result = res.Result.result;
return res.Result.error;
}

The GetAsync function will never return.... and it will hang everything around after that. The reason is explained here:
https://stackoverflow.com/questions/10343632/httpclient-getasync-never-returns-when-using-await-async/10351400#10351400

I looked around the code and one (not nice) solution would be immediately after each Async httpclient task like GetAsync/PostAsync, to call task.Wait(). Of course if you make Async methods you could use the await keyword with the async methods when calling them.

I didn't implement it because I think you know better than I what to do in the SDK and you know Matrix/Synapse much much better than I. Keep on the good job and please don't let me alone in the .NET! 😄

I had the same problem with WPF. You can get around this issue by creating a new thread, and doing all Matrix stuff on that thread, but that is a bit of a hack. I think the only real solution to this problem is just refactoring everything to async.
