AspNet.Identity.EntityFramework

  1. AspNet.Identity.EntityFramework

    With the new release of MVC 5, Microsoft add AspNet.Identity Framwrork, but the AspNet.Identity.EntityFramework only support Code First Pattern, while for Databas/Model First Pattern, it is hard to code all the class by hand. so we add the AspNet.Identity.EntityFramework.tt to support this pattern. You can create you database first and then use this T4 template to automaticly generate the AspNet.Identity compatible classes. There are some limitions:

    1). The table for IdentityRole, IdentityUserClaim, IdentityUserLogin and IdentityUserRole should be same as default schema from AspNet.Identity.EntityFramework (you can use database.init.sql to create the basic schema if you don't konw the schema of the AspNet.Identity.EntityFramework default database).

    2). you can add more columns to the user table but don't remove any default columns from the user table.

  2. Steps:

    1). Install EF Power Tools (http://visualstudiogallery.msdn.microsoft.com/72a60b14-1581-4b9b-89f2-846072eff19d)

    2). Add the T4 template from the NuGet

    3). Run database.init.sql if you have not a databse yet (For Asp.Net Identity Framwork 2.0, you should use database.init.2.0.sql)

    3). Update the const in the T4 template for you need, the consts are: First you should set IDENTITY_LIB_VERSION to the version of Asp.Net Identity Framwork, currently, only 1 and 2 are supported.

     const int IDENTITY_LIB_VERSION = 2;
