how use Custom Membership in website and set in web.config - asp.net

Question

I have Custom Membership Provider in asp.net 4. it's:
public class CustomMembershipProvider : SqlMembershipProvider
{
}
and Custom Role Provider:
public class CustomRoleProvider : RoleProvider
{
}
I use this code for set Custom Membership in web.config:
<membership defaultProvider="CustomMembershipProvider">
<providers>
<clear/>
<add name="CustomMembershipProvider" type="Login1.Code.CustomMembershipProvider" connectionStringName="LoginDB1Entities" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" applicationName="/" />
</providers>
</membership>
<roleManager enabled="true" defaultProvider="CustomRoleProvider">
<providers>
<clear/>
<add name="CustomRoleProvider" type="Login1.Code.CustomRoleProvider" connectionStringName="LoginDB1Entities" applicationName="/" />
<add name="AspNetWindowsTokenRoleProvider" type="System.Web.Security.WindowsTokenRoleProvider" applicationName="/" />
</providers>
</roleManager>
<profile>
<providers>
<clear/>
<add name="AspNetSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider" connectionStringName="ApplicationServices" applicationName="/" />
</providers>
</profile>
and this connection string:
<connectionStrings>
<add name="LoginDB1Entities" connectionString="metadata=res://*/Code.EFModel.csdl|res://*/Code.EFModel.ssdl|res://*/Code.EFModel.msl;provider=System.Data.SqlClient;provider connection string="Data Source=.;Initial Catalog=LoginDB1;Integrated Security=True;MultipleActiveResultSets=True"" providerName="System.Data.EntityClient" />
</connectionStrings>
