How to set up a membership provider to insert data into my own database

You can create a custom MemberhipProvider to work with a custom authentication system. You have to implement many methods. Here's an example

public class DreemMembershipProvider : MembershipProvider
{
...
   public override MembershipUser CreateUser(string username, string password, string email, string passwordQuestion, string passwordAnswer, bool isApproved, object providerUserKey, out MembershipCreateStatus status)
   {
       //your code to insert a user in the db.
   }

   public override bool ValidateUser(string username, string password)
   {
         //your code to check the user and pass against your db 
   }
   ...
}

      

        
        
        
      

    

Finally, you need to configure your application to use the membership provider -> in your web.config file
