Using Async to do a multi-threaded download and update in DataGridView, the runtime in the 4 threads at the same time downloading the interface stutter, after several attempts is not aware of the async and await the thread of the order caused by the call.

After entering the Async method, the code is run in the main thread (the calling thread) after the call to await, and the Async method code that calls await and after will run that part of the code from another thread, and the main thread resumes executing the async code after encountering an await and returning to the main thread.

The Async method is resolved by declaring the delegate after it is called with BeginInvoke.
