我的控制器上出现此错误，'HttpContextBase不包含GetOwinContext的定义，并且没有可访问的扩展方法GetOwinContext接受类型为HttpContextBase的第一个参数”。问题是我现在该如何解决这个问题？命名空间和程序集已在下面定义。我应该做些其他事情来避免此错误吗？请指教并进一步帮助我，谢谢。

GetOwinContext是HttpContext的扩展名，而不是HttpContextBase。试试这个：
HttpContext.ApplicationInstance.Context.GetOwinContext()...
Install-Package Microsoft.Owin.Host.SystemWeb
