有很多建议表明asp.net安装不正确.通常的解决方法是运行:

%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i

要么

%windir%\Microsoft.NET\Framework\v4.0.21006\aspnet_regiis.exe -i

我已经运行了两个,没有任何错误.我已重新启动IIS,但问题仍然存在.该站点正在使用应用程序池.应用程序池已启动,.net framework = 4.0,Managed Pipeline = Classic,Identity = LocalSystem.

我花了最后几个小时试图找出问题所在.我希望有人可以提供帮助.

Answer 1

请按以下步骤操作:

1)以管理员身份运行命令提示符.

2)在命令提示符下键入以下两行中的任何一行:

%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i

要么

%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i

Answer 2

我在新版Windows Server 2012 R2上遇到了这个错误.已安装IIS和.NET 4.5,但尚未添加ASP.NET服务器角色(在我的情况下为4.5版).确保在此屏幕截图中添加/安装了所需的ASP.NET版本,如ASP.NET 4.5.

Answer 3

为了解决这个问题,我试图运行

%windir%\ Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i

但它对我不起作用.我必须以管理员身份在CMD窗口中运行另一个命令行.这是命令:

dism/online/enable-feature/featurename:IIS-ASPNET45

要么

dism/online/enable-feature/featurename:IIS-ASPNET45/all

希望它会有所帮助.
