Migrations Seed Method Ignores Seed Method of Database Initializer

I'm working on an Asp.Net Mvc application then i want to seed my database using custom Database initializer class that I created.

so here is my DbContext :

public class ApplicationDbContext : IdentityDbContext<ApplicationUser> {
    public ApplicationDbContext()
        : base("defaultConnection", throwIfV1Schema: false) {
    }

    static ApplicationDbContext() {
        Database.SetInitializer(new ApplicationDbInitializer());
    }

and here is my ApplicationDbInitializer class :

public class ApplicationDbInitializer : DropCreateDatabaseIfModelChanges<ApplicationDbContext> {

    protected override void Seed(ApplicationDbContext context) {
        InitializeIdentityForEF(context);
        base.Seed(context);
    }

    public static void InitializeIdentityForEF(ApplicationDbContext db) {

        // Create Role Admin if it does not exist
        // Add user admin to Role Admin if not already added
        // And some more initializing stuff

    }
}

Note: I'm using Migrations too.

so when i try to update and seed my database using command Update-Database (even if I delete database manually) , the database is being created but it does not seed it.

if I am doing anything wrong or it has other ways I'll be thankful to get your assistance.

This sounds like the same issue as in this question.

So, the seed code will only run when you create an instance of your ApplicationDbContext.

Add some code like this to your application startup:

var ctx = new ApplicationDbContext();
ctx.Database.Initialize(true);

Then your database will be seeded the next time your app starts.

Alternatively, if you wanted to use the Update-Database command to seed your database, that uses a different Seed method. You can see an example here.
