WebConfig里的配置成员资格角色管理

把连接改一下，先清掉Machine.config里的连接，再加一条，最好名字一样，不然在Asp.net配置那里会有点麻烦。  

<connectionStrings>
     <clear/>
     <add name="LocalSqlServer" connectionString="Data Source=.;Initial Catalog=SocanCRM;Persist Security Info=True;User ID=sa;Password="
       providerName="System.Data.SqlClient" />
</connectionStrings>

然后配置以下三个节点

    <membership>
       <providers>
         <clear/>
         <add name="AspNetSqlMembershipProvider" type="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" connectionStringName="LocalSqlServer" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" applicationName="SocanCRM" requiresUniqueEmail="false" passwordFormat="Hashed" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="4" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" passwordStrengthRegularExpression=""/>
       </providers>
     </membership>
     <profile>
       <properties>
         <add name="UserProfile" type="String" allowAnonymous="false" />
       </properties>
       <providers>
         <clear/>
         <add name="AspNetSqlProfileProvider" connectionStringName="LocalSqlServer" applicationName="SocanCRM" type="System.Web.Profile.SqlProfileProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>
       </providers>
     </profile>
     <roleManager enabled="true">
       <providers>
         <clear/>
         <add connectionStringName="LocalSqlServer" applicationName="SocanCRM" name="AspNetSqlRoleProvider" type="System.Web.Security.SqlRoleProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>
       </providers>
     </roleManager>

profile节里必须有东西才行，不然Profile.UserName一直为空
