解决方案
1、C:/WINNT/Microsoft.NET/Framework/v2.0.50727/aspnet_regsql.exe
用默认的aspnetdb
2、VS:工具(T)-->选项-->数据库工具-->数据连接-->SqlServer实例名称(不要用sqlexp
ress)改为localhost
3、打开VS-->工具-->连接到数据库-->选择服务器-->选择数据库aspnetdb-->高级-->复
制下面的连接字符串Data Source=<localhost>;Initial Catalog=aspnetdb;Integrated
Security=True
4、IIS:默认网站-->属性-->ASP.NET卡-->"编辑全局配置按钮"-->常规卡-->localSqlSe
rver的连接字符串改为
ata Source=<localhost>;Initial
Catalog=aspnetdb;Integrated Security=True
5、IIS:默认网站-->属性-->ASP.NET卡-->"编辑全局配置按钮"-->身份验证卡-->选定"
启用角色管理"
错误:
