问题描述
我想用异步关键字是在.NET 4.0中创建的项目。
I would like to use the async keywords in a project that is created in .net 4.0.
如果我去nuget.org网站，我寻找异步，我很多成果，但主要是我得到这样的：
If I go to the nuget.org website and I look for "async", i many results, but mainly I get this:
的Visual Studio异步CTP（第3版，非官方）0.3.0
这是两者之间的区别是什么？
Which is the differences between both of them?
推荐答案
您想要的 Microsoft.Bcl.Async 包。这是一个正常释放，非CTP包，是稳定的。这也需要VS2012，因为更新的编译器是需要了解异步和等待。
You want the Microsoft.Bcl.Async package. That's a properly released, non-CTP package that is stable. This also requires VS2012 since an updated compiler is needed to understand async and await.
在理论上人们可以使用旧的工具从VS2010随着旧的CTP库，我强烈建议你不这样做 - 它有缺陷，安装本身是一击或错过
In theory one could use older tools from VS2010 along with the older CTP library, I'd strongly recommend that you don't - it has bugs and the installation itself is a hit-or-miss.
