ASP.NET Core disable authentication in development environment

    You can bypass authorization in development environment by applying AllowAnonymousAttribute() to your endpoints. as below code 

 public void Configure(IApplicationBuilder app, IWebHostEnvironment env)

        {

           //-----------------------

            app.UseRouting();

            app.UseEndpoints(endpoints =>

            {

                if (env.IsDevelopment())

                    endpoints.MapControllers().WithMetadata(

                        new AllowAnonymousAttribute());

                else

                    endpoints.MapControllers();

            });

        //---------------------------
