这是在我安装了Nuget-Package Microsoft.AspNet.WebApi.Cors之后发生的，首先它甚至没有在本地工作，但后来我设法使用Nuget-Package Manager Commando“Update-Package”。

Answer 1

请使用此命令在服务器中重新安装ASP.Net

aspnet_regiis.exe -i

这会将ASP.net设置为正确并使其正常工作

Answer 2

您可以简单地安装软件包：

 Install-Package Microsoft.AspNet.WebApi -Version 5.2.3

或收到错误的版本。

ASP.NET Web-Api在本地工作，但在IIS7上部署后却没有
