First time trying to deal with users logging in with ASP.net and haven’t had much experience with it with other things. From searching, I am seeing things like Asp.Net MVC Membership Provider. Is this a built in thing?
Is there any good online guides for this?
Take a look at the ASP.NET Provider Model. The MembershipProvider is a provider in the built-in provider model for handling users and you can download the source code of the default providers to look at how they are implemented.
If you want to install the default provider databases on a sql server, you can run Aspnet_regsql.exe from the command line to do so.
The great thing about the provider model is that it is very straightforward to write your own providers by deriving from the abstract base classes and use them in an application. You need only implement the methods that you need.
