Authentication and Authorization without Entity Framework in ASP.NET 5 MVC 6

Authentication and Authorization without Entity Framework in ASP.NET 5 MVC 6

Yes, it is possible to implement authentication and authorization without using Entity Framework in ASP.NET 5 MVC 6.

To implement authentication and authorization, you can use ASP.NET Core Identity, which is a membership system that provides authentication and authorization capabilities. It is not tightly coupled to any specific data store and can be used with a custom user data store implementation.

Here are the steps to use ASP.NET Core Identity without Entity Framework:

  1. Add the required NuGet packages:

    Microsoft.AspNetCore.Identity Microsoft.AspNetCore.Identity.EntityFrameworkCore

  2. Implement the IUserStore<TUser> and IRoleStore<TRole> interfaces to provide user and role data store functionality. You can use any data store, such as a SQL database, NoSQL database, or even a file-based storage.

  3. Configure the Identity middleware in the Startup.cs file:

    services.AddIdentity<ApplicationUser, ApplicationRole>() .AddUserStore<CustomUserStore>() .AddRoleStore<CustomRoleStore>() .AddDefaultTokenProviders();

    where ApplicationUser and ApplicationRole are your custom user and role models.

  4. Configure authentication middleware:

    services.AddAuthentication(options => { options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme; options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme; }).AddJwtBearer(options => { options.RequireHttpsMetadata = false; options.SaveToken = true; options.TokenValidationParameters = new TokenValidationParameters { ValidateIssuerSigningKey = true, IssuerSigningKey = new SymmetricSecurityKey(Encoding.ASCII.GetBytes(Configuration["Jwt:Key"])), ValidateIssuer = false, ValidateAudience = false }; });

  5. Use the Authorize attribute to secure your controller actions and views:

    [Authorize(Roles = "Admin")] public IActionResult AdminDashboard() { return View(); }

These steps provide a basic implementation of authentication and authorization in ASP.NET 5 MVC 6 without using Entity Framework.
