Creating Roles in Asp.net Identity MVC 5

Question

There is very little documentation about using the new Asp.net Identity Security Framework.

I have pieced together what I could to try and create a new Role and add a User to it. I tried the following: Add role in ASP.NET Identity

which looks like it may have gotten the info from this blog: building a simple to-do application with asp.net identity and associating users with to-does

I have added the code to a Database Initializer that is run whenever the model changes. It fails on the RoleExists function with the following error:

System.InvalidOperationException occurred in mscorlib.dll The entity type IdentityRole is not part of the model for the current context.

protected override void Seed (MyContext context) {     var UserManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(context));      var RoleManager = new RoleManager<IdentityRole>(new RoleStore<IdentityRole>(context));      // Create Admin Role     string roleName = "Admins";     IdentityResult roleResult;      // Check to see if Role Exists, if not create it     if (!RoleManager.RoleExists(roleName))     {         roleResult = RoleManager.Create(new IdentityRole(roleName));     } } 

Any help is appreciated.

Here we go:

var roleManager = new RoleManager<Microsoft.AspNet.Identity.EntityFramework.IdentityRole>(new RoleStore<IdentityRole>(new ApplicationDbContext()));      if(!roleManager.RoleExists("ROLE NAME"))    {       var role = new Microsoft.AspNet.Identity.EntityFramework.IdentityRole();       role.Name = "ROLE NAME";       roleManager.Create(role);      }
