'await' works, but calling task.Result hangs/deadlocks

Question

I have the following four tests and the last one hangs when I run it. Why does this happen:

[Test]
public void CheckOnceResultTest()
{
    Assert.IsTrue(Check         


        

Answer 1

If you don't get any callbacks or the control hangs up, after calling the service/API async function, you have to configure Context to return a result on the same called context.

Use TestAsync().ConfigureAwait(continueOnCapturedContext: false);

You will be facing this issue only in web applications, but not in static void main.
