Version Information: Microsoft .NET Framework Version:2.0.50727.5448; ASP.NET Version:2.0.50727.5456

 

发生上面问题的主要原因是当前vs工程使用的时.NET4.0的版本，而IIS上默认的该website的.Net Framework Version 是低于4.0的版本

 

打开 IIS: 自己电脑名字 -> Application Pools ->website名字->右键单击->选择“Basic setting...” -> “.Net Framework version”(选择 .Net Framework v4.0)->确定。

如果不起作用关掉IIS，重新打开一下

 

Open  IIS: "My computer name" -> Application Pools -> your website name(.Net Framework Version)->right click->Basic setting... -> .Net Framework version(select .Net Framework v4.0)->OK

如果想一劳永逸那就直接选择“Set Application Pool Default...”，在里面的 ”.Net Framework version“选择"v4.0"，关闭IIS重新打开全部会设置为4.0版本的.NET Framework version。
