Blazor .Net 9 Default template simple usage of a service - porting from an earlier version

Question

I tried to port this simple project:

https://github.com/JWealthall/BlazorWindowResize

to .net 9.0

So, I created a simple sample at:

https://github.com/KKacer/BlazorTestWindowSize

I'm trying to understand the usage and changes I need to do in the 2 Program.cs files (one in the Client project, and the other in the Server project)

What I did was placing all the Interfaces, Services and Models inside the Client project.

But using the same Program.cs which was implemented in that project may not work here:

using BlazorWindowResize;

using BlazorWindowResize.Interfaces;

using BlazorWindowResize.Services;

using Microsoft.AspNetCore.Components.Web;

using Microsoft.AspNetCore.Components.WebAssembly.Hosting;

var builder = WebAssemblyHostBuilder.CreateDefault(args);

builder.RootComponents.Add<App>("#app");

builder.RootComponents.Add<HeadOutlet>("head::after");

builder.Services.AddScoped(sp => new HttpClient { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) });

builder.Services.AddScoped<IBrowserService, BrowserService>();

var host = builder.Build();

await host.Services.GetRequiredService<IBrowserService>().Init();

await host.RunAsync();

Should I add part of these implementations in the Server project? What changes are needed and why?

Thanks in advance for any help.

Answer 1

you will need to add the service in both projects. The server project will need the service for server interactive or client static pre-render. The client project when used as WASM will also need the service.

Answer 2

Thanks for the hint,

with some edits, I was able to figure it out.
