Unravel.AspNet.Identity.EntityFramework

Unravel.AspNet.Identity.EntityFramework

Unravel provides AddIdentity() extension methods on IServiceCollection. The resulting IdentityBuilder provides methods and an extension point to configure Microsoft.AspNet.Identity services:

• AddEntityFrameworkStores<TContext>() registers a context inheriting from IdentityDbContext<>, plus dependent store implementations
  • Calls SetPerOwinContext<T>(), from Unravel.AspNet.Identity, replacing CreatePerOwinContext<T>()

This is designed to directly migrate from the scaffolded Startup.Auth.cs pattern:

public void ConfigureAuth(IAppBuilder app)
{
    // Configure the db context, user manager and signin manager to use a single instance per request
    app.CreatePerOwinContext(ApplicationDbContext.Create);
    app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
    app.CreatePerOwinContext<ApplicationSignInManager>(ApplicationSignInManager.Create);
    // ...
}

To:

public override void ConfigureServices(IServiceCollection services)
{
    services.AddIdentity<ApplicationUser>()
        .AddEntityFrameworkStores(ApplicationDbContext.Create)
        .AddUserManager<ApplicationUserManager>(ApplicationUserManager.Create)
        .AddSignInManager<ApplicationSignInManager>(ApplicationSignInManager.Create)
}

You can then refactor away from the Create methods to constructor injection, e.g.
