Question

我们有以下环境：

1）第三方桌面应用程序App.exe针对.Net 4.0。

2）我们的plugin.dll以.Net 4.0为目标，由App.exe动态加载。

3）我们的插件使用Microsoft.Bcl.Async。

4）随着我们的插件，我们分发：

Microsoft.Threadng.Tasks.dll
Microsoft.Threadng.Tasks.Extensions.dll
Microsoft.Threadng.Tasks.Extensions.Desktop.dll
System.Threading.Tasks.dll
System.IO.dll
System.Runtime.dll

所以，最后我们在客户端系统上有以下目录结构：

App /
    App.exe
    App.config
    plugin.dll
    Microsoft.Threadng.Tasks.dll
    Microsoft.Threadng.Tasks.Extensions.dll
    Microsoft.Threadng.Tasks.Extensions.Desktop.dll
    System.Threading.Tasks.dll
    System.IO.dll
    System.Runtime.dll

我们的问题是，如果客户端系统安装了.Net 4.5，一切正常，但如果客户端系统有.Net 4.0，则App.exe无法加载我们的插件：

System.IO.FileLoadException 无法加载文件或程序集“System.Threading.Tasks，Version = 1.5.11.0，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a＆＃39;或其中一个依赖项。定位的程序集清单定义与程序集引用不匹配。

如果我们修改App.config以从我们的发行版重定向绑定到System.Threading.Tasks，那么错误就会消失。但我认为这不是一个好的解决方案。

我强烈认为我们做错了什么，但我没有足够的.Net经验来正确解决这个问题。

另外，我的猜测是正确的，Bcl.Async允许代码定位到.Net 4.0使用async / await而不需要重新定位到.Net 4.5吗？

任何人都可以帮助我吗？

如何在.Net 4.0中使用和部署Microsoft.Bcl.Async？
