A9 Security: Authorization (ApplicationRoleManager) (Wpf, Xamarin) - chempkovsky/CS2WPF-and-CS2XAMARIN GitHub Wiki

To add a custom ApplicationRoleManager implementation to your project, follow these steps:

• With Visual studio 2019 open Dm04WebApp.csproj project
• open App_Start\IdentityConfig.cs-file
• insert the code below right after the definition of ApplicationUserManager {...}-class

    public class ApplicationRoleManager : RoleManager<IdentityRole>
    {
        public ApplicationRoleManager(IRoleStore<IdentityRole, string> roleStore) : base(roleStore)
        {
        }

        public static ApplicationRoleManager Create(IdentityFactoryOptions<ApplicationRoleManager> options, IOwinContext context)
        {
        ///It is based on the same context as the ApplicationUserManager
            var appRoleManager = 
                new ApplicationRoleManager(new RoleStore<IdentityRole> (context.Get<ApplicationDbContext> ()));
            return appRoleManager;
        }
    }

• open App_Start\Startup.Auth.cs-file
• find ConfigureAuth(IAppBuilder app){ ... }-method.
• Place the cursor immediately after the line of code: app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);

           public void ConfigureAuth(IAppBuilder app)
            {
                ...
                app.CreatePerOwinContext(ApplicationDbContext.Create);
                app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
                --PLACE CURSOR HERE--

• Insert the following line of code: app.CreatePerOwinContext<ApplicationRoleManager>(ApplicationRoleManager.Create);
• Here is a result

            public void ConfigureAuth(IAppBuilder app)
            {
                ...
                app.CreatePerOwinContext(ApplicationDbContext.Create);
                app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
                app.CreatePerOwinContext<ApplicationRoleManager>(ApplicationRoleManager.Create);
                ...
