【问题描述】：

我使用 Yeoman asp.net 生成器中的模板创建了一个 asp.net Web API 项目。我可以使用 dnu build 命令成功构建它，但是当我运行 dnx web 时，它给了我这个错误：

  System.IO.FileLoadException: Could not load file or assembly 'System.Threading.Overlapped, Version=4.0.1.0, Culture=neut
ral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The located assembly's manifest definition does not ma
tch the assembly reference. (Exception from HRESULT: 0x80131040)

我在 windows 7 x64 上使用 coreclr 1.0.0-rc1-15798 coreclr x64。我可以从 https://github.com/aspnet/home

运行模板

project.json 文件：

【问题讨论】：

不要混用 beta7 和 rc

【解决方案1】：

使用 dnx beta7。不要将 beta7 与 beta8 或 rc1 位混合
