Few steps to follow:
- Install NuGet Package:
Microsoft.AspNet.Identity.EntityFramework
- Add a
connection string to your web.config/app.config
Now you have to define your custom Database Context:
public class MyContext : IdentityDbContext
{
public MyContext()
: base(<connection string name>)
{
}
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
modelBuilder.Entity<IdentityUser>()
.ToTable("Users");
modelBuilder.Entity<IdentityRole>()
.ToTable("Roles");
modelBuilder.Entity<IdentityUserRole>()
.ToTable("UserRoles");
modelBuilder.Entity<IdentityUserClaim>()
.ToTable("UserClaims");
modelBuilder.Entity<IdentityUserLogin>()
.ToTable("UserLogins");
}
}
As you can see I've used DbModelBuilder to map all the entities to a new tables.
- Open NuGet Package Manager Console
- Execute command
Enable-Migrations
It will create a folder Migrations with the configuration file Configuration.cs.
It should look something like this:
internal sealed class Configuration : DbMigrationsConfiguration<ConsoleApplication1.Models.MyContext>
{
public Configuration()
{
AutomaticMigrationsEnabled = false;
}
protected override void Seed(ConsoleApplication1.Models.MyContext context)
{
}
}
In the constructor change the property AutomaticMigrationsEnabled to true.
- Open NuGet Package Manager Console
- Execute command
Update-Database
It should run the script to create the new tables.
You can customize your entities (and Ids) creating custom class for each interface defined.
public class MyUser : IdentityUser<string, MyUserLogin, MyUserRole, MyUserClaim>
{
}
Since you're using Owin you can define your UserStore:
public class MyUserStore: UserStore<MyUser, MyRole, string, MyUserLogin, MyUserRole, MyUserClaim>
{
public MyUserStore(MyContext context)
: base(context)
{
}
}
and your UserManager implementation:
public class ApplicationUserManager : UserManager<ASPNETIdentity2.Models.MyUser, string>
{
public ApplicationUserManager(IUserStore<ASPNETIdentity2.Models.MyUser, string> store)
: base(store)
{
}
public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options, IOwinContext context)
{
var manager = new ApplicationUserManager(new MyUserStore(context.Get<MyContext>()));
manager.UserValidator = new UserValidator<MyUser, string>(manager)
{
AllowOnlyAlphanumericUserNames = false,
RequireUniqueEmail = true
};
manager.PasswordValidator = new PasswordValidator()
{
RequiredLength = 5,
RequireNonLetterOrDigit = false, // true
// RequireDigit = true,
RequireLowercase = false,
RequireUppercase = false,
};
return (manager);
}
}
And your Owin.Startup should look something like this:
public class Startup
{
public void Configuration(IAppBuilder app)
{
app.CreatePerOwinContext(MyContext.Create);
app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
}
}
If you want to have a look at a custom implementation you can check my GitHub repository with a simple working solution on ASP.NET MVC.
UPDATE:
There's another project in that solution with a minimal setup; basically you only need to define your context (IdentityDbContext) if you only want to rename your tables.
The project can be found here.
