 -1:     0:  

Cause：1) 没有向iis中注册.net framework（引起的原因之一：先安装了.net framework，后安装的iis）

　　　　2) 没有对IIS中所配置的site有足够的操作权限（Modify权限）

Solution：

　　　　1) 到C:\Windows\Microsoft.NET\Framework64\v2.0.50727下，

　　　　　 用命令向iis中重新注册一下.net framework：aspnet_regiis -i

　　　　2) IIS Manager --> Sites --> 相应的site --> 点击右键 --> Edit Permissions --> Security --> Group or user names --> Edit --> Add--> 添加赋予Full Control权限（实质上带有Modify的权限就可以）的Everyone用户

Configuration Error

Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately. 

Parser Error Message: Unrecognized attribute ‘targetFramework‘. Note that attribute names are case-sensitive.

Version Information: Microsoft .NET Framework Version:2.0.50727.4963; ASP.NET Version:2.0.50727.4955

Cause：当前程序所运行的.NET Framework版本与IIS中相应site所设置的.NET Framework版本不相同

Solution：启动IIS Manager --> Application Pools --> 选择相应的Name（site） --> 点击右键 --> Advanced Settings --> （General）.NET Framwork Version --> 由2.0更改到4.0即可

Cause：IIS中的Application pool中相应site的Identity类型错误

Solution: IIS Manager --> Application Pools --> 找到相应的site --> 左键选择Advanced Settings --> 将Process Model中的Identity类型换成LocalSystem
