我从1and1购买了共享的Windows托管计划。上传了默认的Visual Studio“网页”网站后，我在1and1上收到以下错误。考虑到这是默认的Microsoft模板，至少我感到非常惊讶。
任何人都能提供的帮助，我将不胜感激。
非常感谢。

最佳答案
您的托管人(1and1)强制网站以“中等信任度”运行。中度信任已过时，并且ASP.NET不再支持它。有关更多信息，请参见https://stackoverflow.com/a/17218344/59641和http://support.microsoft.com/kb/2698981。
您可以尝试说服1and1以Full Trust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。
