.NET 6 compability seems to be broken or I'm doing something wrong

Hello,

So I followed the tutorial on how to implement a modal/banner,

My Startup.cs:

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.HttpsPolicy;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Majorsoft.Blazor.Components.GdprConsent;

namespace _34digital.ruhr
{
    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            //Register dependencies
            services.AddGdprConsent();
            services.AddRazorPages();
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseExceptionHandler("/Error");
                // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
                app.UseHsts();
            }

            app.UseHttpsRedirection();
            app.UseStaticFiles();

            app.UseRouting();

            app.UseAuthorization();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapRazorPages();
            });
        }
    }
}

No errors appeared here. But as soon as I add the code for the banner/modal into _Layout.cshtml or any new shared razor page I get a lot of errors. The most common error type is Name X is not available in current context. Here’s a screenshot of the errors marked.

I am using .NET Core 6 (Blazor) on Visual Studio 2022 Preview 3.1

P.S. yes I’m a beginner at .NET Core and C# in general

Thank you so much for answering this so in-depth and even though it was completely not related to your component, I really really appreciate it!

Partially true… When you create a Blazor WASM application (client side) then yes it is true. But Blazor is super flexible it has many hosting models. You can have server side/server hosted Balzor with different render options. Check out render-mode options there is even a “hybrid” where your app renders some HTML to show in the browser (this HTML can have meta tags) and then app will switch to WASM mode.

So Blazor is not a SPA framework as you might think. It is a component based “Web” application framework. And even “WEB” is in quotes since Blazor will be everywhere pretty soon… If not there already… If you write your Blazor components correctly (e.g. no DB or private resource access in the components which will fail on WASM mode) then you can use the SAME components in all apps below:

• Browser client side SPA with WASM
• Server side hosting or even rendered or Hybrid render than switch to WASM
• Existing MVC applications also can host some Blazor components
• Blazor Electron for Chromium based desktop applications
• WebWiew components added to MS desktop apps like WinFroms and WPF so Blazor components can be shown in existing even super old windows desktop apps.
• Blazor Flutter for native Mobile apps, since Blazor also very modular so MS now can switch the component tree renderer from HTML to Flutter mobile UI renderer…

Even at any point in time you just “port” your application from Server side to WASM or Electron on Mobile with “minimal” effort… Hope this answered your questions.
