I am trying to get the database to be created ONLY if it does not exist but am not being successful. I only replaced DropCreateDatabaseAlways() and replaced it with CreateDatabaseIfNotExists(). Do you think that is all I have to do?

Here is what my ApplicationDbInitializer() now looks like:

public class ApplicationDbInitializer : CreateDatabaseIfNotExists<ApplicationDbContext>
{
    protected override void Seed(ApplicationDbContext context)
    {
        InitializeIdentityForEF(context);
        base.Seed(context);
    }

    //Create [email protected] with password=Admin@123456 in the Admin role        
    public static void InitializeIdentityForEF(ApplicationDbContext db)
    {
        var userManager = HttpContext.Current.GetOwinContext().GetUserManager<ApplicationUserManager>();
        var roleManager = HttpContext.Current.GetOwinContext().Get<ApplicationRoleManager>();
        const string name = "[email protected]";
        const string password = "Admin@123456";
        const string roleName = "Admin";

        //Create Role Admin if it does not exist
        var role = roleManager.FindByName(roleName);
        if (role == null)
        {
            role = new ApplicationRole(roleName);
            var roleresult = roleManager.Create(role);
        }

        var user = userManager.FindByName(name);
        if (user == null)
        {
            user = new ApplicationUser { UserName = name, Email = name };
            var result = userManager.Create(user, password);
            result = userManager.SetLockoutEnabled(user.Id, false);
        }

        // Add user admin to Role Admin if not already added
        var rolesForUser = userManager.GetRoles(user.Id);
        if (!rolesForUser.Contains(role.Name))
        {
            var result = userManager.AddToRole(user.Id, role.Name);
        }
    }
}

would be awesome to have it as a real template in create new project.

First of all, thank you for your tutorial on your site and the example code. I am a lover of extremely long identifiers and thought I would try my hand at using Guid as the type for the key (since you were able to use the extension method to use int, I thought it should be as simple as a find/replace, but it would seem it is not. Have you tried this and if so, how were you able to get around the issue:

Can I to use it with web forms project?

Hi John,

Received the following error in IdentitySample.Startup.ConfigureAuth at the app.UseCookieAuthentication call on line 25.

It is on a brand new build, no database setup yet.

{System.FormatException: Input string was not in a correct format
at System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal)
at System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info)
at System.Int32.Parse(String s)
at IdentitySample.Startup.b__3(ClaimsIdentity claim) in c:\Users\Riaan\Documents\Visual Studio 2013\Samples\AspNetIdentity2IntegerKeys\IdentitySample\App_Start\Startup.Auth.cs:line 37
at Microsoft.AspNet.Identity.Owin.SecurityStampValidator.<>c__DisplayClass2`3.<b__1>d__4.MoveNext()}

Web output:

Line 35: regenerateIdentityCallback: (manager, user) => user.GenerateUserIdentityAsync(manager),
Line 36: // Need to add THIS line because we added the third type argument (int) above:
Line 37: getUserIdCallback: (claim) => int.Parse(claim.GetUserId()))
Line 38: }
Line 39: });

Any suggestions?

I think the logic for ConfirmEmail got messed up when changing the null check of string to a > 0 check for an int.

It should be something like:

if(userId > 0 && code != null){
//Do success stuff
}
//Do Error stuff

Compiler Error Message: CS0234: The type or namespace name 'Ajax' does not exist in the namespace 'System.Web.Mvc' (are you missing an assembly reference?).

Fixed by cleaning the project, going to References, Properties of the System.web.mvc and setting copy local true.

When I open this project in VS2013 SP3 most of the references are not available. This appears to be because you have used NuGet to download the references. How can I fix this problem easily?
