// Three things to note in the signature://  - The method has an async modifier. //  - The return type is Task or Task<T>. (See "Return Types" section.)//    Here, it is Task<int> because the return statement returns an integer.//  - The method name ends in "Async."async Task<int> AccessTheWebAsync(){     // You need to add a reference to System.Net.Http to declare client.    HttpClient client = new HttpClient();    // GetStringAsync returns a Task<string>. That means that when you await the    // task you‘ll get a string (urlContents).    Task<string> getStringTask = client.GetStringAsync("http://msdn.microsoft.com");    // You can do work here that doesn‘t rely on the string from GetStringAsync.    DoIndependentWork();    // The await operator suspends AccessTheWebAsync.    //  - AccessTheWebAsync can‘t continue until getStringTask is complete.    //  - Meanwhile, control returns to the caller of AccessTheWebAsync.    //  - Control resumes here when getStringTask is complete.     //  - The await operator then retrieves the string result from getStringTask.    string urlContents = await getStringTask;    // The return statement specifies an integer result.    // Any methods that are awaiting AccessTheWebAsync retrieve the length value.    return urlContents.Length;}
