ASP.NET membership is designed to enable you to easily use a number of different membership providers for your ASP.NET applications. You can use the supplied membership providers that are included with the .NET Framework, or you can implement your own providers.

There are two primary reasons for creating a custom membership provider.

  • You need to store membership information in a data source that is not supported by the membership providers included with the .NET Framework, such as a MysQL database, an Oracle database, or other data sources.
  • You need to manage membership information using a database schema that is different from the database schema used by the providers that ship with the .NET Framework. A common example of this would be membership data that already exists in a SQL Server database for a company or Web site.

In tis tutorial, we are going to implement and configure a custom Membership Provider using ASP.NET MVC4

Let’s go

  3. Create a Class CustomMembershipProvider and derive it from MembershipProvider
  4. Override ValidateUser as follow

For now we have what we need for our application security.  To go further in the implementation of Custom Membership Provider, please see our tutorial Mastering Custum ASP.NET MemberShip Provider using ASP.NET MVC

B.  Create an ASP.NET MVC4 application Client

1.       Create an ASP.NET MVC4 application Client ( Add New projet è ASP.NET MVC4 Web Application è Select Template Internet Web Appliction and Click OK)
2.       Open Web.config file
3.       Add or Replace membership section as follow
