我的asp.net core应用在桌面上可以正常运行。但是当我部署到Windows Server 2007 R2时，出现了以下错误。

Application startup exception: System.DllNotFoundException: Unable to load DLL 'api-ms-win-core-registry-l1-1-0.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

我有同样的问题和困扰。对我来说，错误的原因是我在Windows 10上开发，但部署到了Windows 2008 R2上。

解决方法是编辑你的project.json文件，将runtimes设置为win7-x64。

原始内容：

 "runtimes": {
    "win10-x64": {}
  },

固定：

 "runtimes": {
    "win7-x64": {}
  },

我曾尝试同时使用两个运行时，但发布失败了。

请确保您的“目标运行时”发布设置已设置为win7-x64：
