我已经从 1and1 购买了共享 Windows 托管计划。上传默认的 Visual Studio“网页”站点后，我在 1and1 上收到以下错误。考虑到这是 Microsoft 的默认模板，至少可以说我感到非常惊讶。
如果有人能够提供任何帮助，我将不胜感激。
非常感谢。

最佳答案
您的托管商(1 和 1)强制网站以中等信任度运行。 Medium Trust 已过时，ASP.NET 以后不再支持它。参见 https://stackoverflow.com/a/17218344/59641和 http://support.microsoft.com/kb/2698981获取更多信息。
您可以尝试说服 1and1 以完全信任的方式运行您的网站。否则，您应该考虑转移到允许完全信任的新主机。
