Use awaiter and callback In this approach the UI client calls the service layer and passes a callback to the service layer, the service layer wraps the http call to the server in a task and use GetAwaiter ().GetResult (), when the http call is finished it invokes the callback passed by the UI client. In this case no method has to marked async .

As I describe on my blog, GetAwaiter().GetResult() can deadlock when it's used in a one-thread-at-a-time context.This is most commonly seen when called on the UI thread or in an ASP.NET context (for pre-Core ASP.NET). Wait has the same problems. The appropriate fix is to use await, and make the calling code asynchronous.. Note that .The problem then is that extension methods don't work with dynamic. What you can do is to explicitly specify that you're working with a Task, which means the extension method will work, and then switch back to dynamic: dynamic request = new SerializableDynamicObject(); request.Operation = "test";问题：GetAwaiter是什么？. 回答：在C#中，如果你用await进行异步操作，那么编译器会去调用这个异步表达式的GetAwaiter方法，例如. 代码块:await Task.Delay(5) 编译器翻译过来:TaskAwaiter awaiter = Task.Delay(5).GetAwaiter. 至于await是什么，baidu,google很多人已经解释过，不赘述.public: System::Runtime::CompilerServices::ValueTaskAwaiter GetAwaiter(); public System.Runtime.CompilerServices.ValueTaskAwaiter GetAwaiter (); member this .

In this article. Async methods can have the following return types: Task, for an async method that performs an operation but returns no value.; Task, for an async method that returns a value. void, for an event handler.; Any type that has an accessible GetAwaiter method. The object returned by the GetAwaiter method must .T result = task.GetAwaiter().GetResult(); The code above will synchronously block until the task completes. As such, it is subject to the same old deadlock problems as Wait and Result. However, it will not wrap the task exceptions in an AggregateException. The code above will retrieve the result value from a Task.
