问题 I'm trying to start a task after I register a continuation for it. But continuation fires immediately after await Task.Delay() is called. using System; using System.Linq; using System.Threading.Tasks; namespace ConsoleApplication30 { class Program { static void Main(string[] args) { var task = new Task(async delegate { Console.WriteLine("Before delay"); await Task.Delay(1000); Console.WriteLine("After delay"); }); task.ContinueWith(t => { Console.WriteLine("ContinueWith"); }); task.Start();

问题 .net 4.6 framework is inplace upgrade then how is the .net framework 4.5 works in vs2015? I see only one folder v4.0.30319 . How is the dll stored and where ? 回答1: Update : Note that Reference Assemblies only contain metadata and NOT any code at all. Thanks @vcsjones for pointing this out below!
