Create an empty project

After creating an empty project, install the three packages through NuGet.

• Nancy
• Nancy. Hosting. Aspnet
• Nancy. ViewEnglines. Razor

Add the three folders Models, Module, and Views to the project, and add the UserModel class to Models.

        public string  Username { get; set; }        public UserModel(string username)        {            this.Username = username;        }

Add the MainModule class to the Module folder.

 Get("/", Lexan => { return View["index.cshtml"]; });            Get("/login", Lexan => { return View["login.cshtml",this.Request.Query.returnUrl]; });

Then add the SecureModule class and the AnotherVerySecureModule class.

        public SecureModule():base("/secure")        {            this.RequiresAuthentication();            Get("/",Lexan=>            {                var model = new UserModel(this.Context.CurrentUser.Identity.Name);                return View["secure.cshtml",model];            });        }

 public AnotherVerySecureModule():base("/superSecure")        {            this.RequiresClaims(Lexan=>Lexan.Type==ClaimTypes.Role&&Lexan.Value=="SuperSecure");            Get("/",Lexan=>             {                var model = new UserModel(this.Context.CurrentUser.Identity.Name);                return View["superSecure.cshtml",model];            });        }

Add the AuthenticationBootstrapper class to the root directory

        protected override void ApplicationStartup(TinyIoCContainer container, IPipelines pipelines)        {            base.ApplicationStartup(container, pipelines);            pipelines.BeforeRequest += ctx =>              {                  var username = ctx.Request.Query.username;                  if (username.HasValue)                  {                      ctx.CurrentUser = new ClaimsPrincipal(new ClaimsIdentity(BuildClaims(username), "querystring"));                  }                  return null;              };            pipelines.AfterRequest += ctx =>              {                  if (ctx.Response.StatusCode==HttpStatusCode.Unauthorized)                  {                      ctx.Response = new RedirectResponse("/login?retutnUrl="+ Uri.EscapeDataString(ctx.Request.Path));                  }              };        }        private static IEnumerable<Claim> BuildClaims(string userName)        {            var claims = new List<Claim>();            if (String.Equals(userName,"Lexan",StringComparison.OrdinalIgnoreCase))            {                claims.Add(new Claim(ClaimTypes.Role,"SuperSecure"));            }            return claims;        }

Add View index, login, secure, and superSecure in Views.
