Custom membership provider implementation for the ADO.NET Entity Framework.


Note: This article has been superseded by the following code project article. 

This article describes the implementation of a custom membership provider for the ADO.NET entity framework. The code presented in this article fully complies with Microsoft's provider model design pattern. It also leverages the LINQ to Entities feature introduced with framework 3.5.


It is required to have a basic understanding of the ADO.NET Entity Framework and the ASP.NET membership provider model in order to successfully integrate the presented solution.

Using the code

To configure the attached sample, the following steps have to be taken into account:

  1. Create a database (e.g., EFDataModel).
  2. Run the CreateUserTable.sql script located in the DatabaseScripts solution folder.
  3. Modify the connection string for the Entity Framework in the App.config file of the SmartSoft.EFMembershipProvider.DataLayer project.
  4. Modify connection string for the Entity Framework in the Web.config file of the Web application.

If you want to integrate the custom membership provider into your existing application, you might have to replace the object context EFDataModelEntities within the membership provider class according to your entity model.

Depending on your data model, the method DeleteUser within the membership provider class has to be extended from line 698 onwards in order to delete/mark all user related data.

Michael Ulmann has posted a reply to your message at "Article "Custom membership provider for the entity framework"":

If you understood the MS membership provider you would know that this is just covering the same functionality as the SqlMembershipProvider. It does not make sense at all to dump heaps of lines of code that are straight forward implemented.


Actually, I DO understand the membership provider. But, I'm not the next guy reading this "article". I have to think about the newbie comming in behind me that might NOT understand the provider. You leave it entirely up to the reader to decipher your code, which is NOT good way to teach someone about it.
