问题描述

大家好，



如何在我安装的c＃窗口应用程序中使用Await和async关键字都需要像 Nuget 但我仍然无法找到await或async关键字Vs2010。



请帮助...

Hi all,

How Can Use Await and async keywords in my c# window application i already installed all require Software like Nuget but still i am not able to find await or async keyword in my Vs2010.

Please Help...

推荐答案

你不能。 Await和Async在V4.5上添加，所以你最好的选择是将VS升级到2013.

你不能在VS2010中使用那个只有C＃4.0

You can't. Await and Async were added at V4.5 so your best bet is to upgrade VS to 2013.
You can't use then in VS2010 which is "only" C# 4.0
