'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

Acquiring a value via an async method:

var result = Task.Run(() => asyncGetValue()).Result;

Syncronously calling an async method

Task.Run( () => asyncMethod()).Wait();

No deadlock issues will occur due to the use of Task.Run.
