Could not load type System.ServiceModel.Activation.HttpModule解决办法

1. 部署网站到IIS7.5,Window 2008的时候出现这个错误 

 
2. 错误信息 Server Error in ‘/’ Application. Could not load type ‘System.ServiceModel.Activation.HttpModule’ from assembly ‘System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089′. 
 
3. 解决办法 
 
这里需要注册一下ASP.NET 4.0 
在命令窗口里运行一下命令即可: aspnet_regiis.exe /iru 
 
The aspnet_regiis.exe file can be found in either
%windir%\Microsoft.NET\Framework\v4.0.30319 
%windir%\Microsoft.NET\Framework64\v4.0.30319 (on a 64-bit machine)
 
一般默认的系统目录不变的话,应该是一下语句
C:/Windows/Microsoft.NET/Framework/v4.0.30319/aspnet_regiis.exe -iru

以上信息是否已解决您的问题?
