How can I do this without having to duplicate the GenerateCodeAsync method in order for this to work synchronously? Update Yet no reasonable solution found. However, I … Read more
What is the difference between the below code snippets? Won’t both be using threadpool threads?

Preface: I’m looking for an explanation, not just a solution. I already know the solution. Despite having spent several days studying MSDN articles about the Task-based Asynchronous Pattern (TAP), async and await, I’m still a bit confused about some of the finer details. I’m writing a logger for Windows Store Apps, and I want to … Read more
I’ve got an interface which declares Task DoSomethingAsync(); I’m using MoqFramework for my tests: [TestMethod()] public async Task MyAsyncTest() { Mock<ISomeInterface> mock = new Mock<ISomeInterface>(); mock.Setup(arg => arg.DoSomethingAsync()).Callback(() => { <my code here> }); … } Then in my test I execute the code which invokes await DoSomethingAsync(). And the test just fails on that … Read more
In C# 4.0, we have Task in the System.Threading.Tasks namespace. What is the true difference between Thread and Task.

I have initially searched in Stackoverflow for … Read more
