Problem with add Security

Radzen Blazor Studio
1

I added the project with a username and password, so I went to the "security" button.
After the security addition process, no page can be rendered. Even in VS 2022, it doesn't work either.

What is the cause of this error?

System.InvalidOperationException: Cannot provide a value for property 'DialogService' on type 'Mttoplus2.Components.Layout.LoginLayout'. There is no registered service of type 'Radzen.DialogService'.

I am using the following versions:

Radzen Blazor Studio 1.41.2

Make sure you added required services and components as per our getting started instructions:

The changes were made when the Button was applied:

Up to this point the rendering of the pages worked correctly/

in MainLayout.razor append the suggested:

@inherits LayoutComponentBase

@inject Microsoft.Extensions.Localization.IStringLocalizer L

<RadzenComponents @rendermode="InteractiveAuto" />
...

in programs.cs:

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.

builder.Services.AddRazorComponents().AddInteractiveServerComponents().AddHubOptions(options => options.MaximumReceiveMessageSize = 10 * 1024 * 1024);

builder.Services.AddRadzenComponents();

builder.Services.AddHttpClient();

builder.Services.AddScoped<Mttoplus2.mtto2Service>();

builder.Services.AddScoped();

builder.Services.AddScoped();

builder.Services.AddScoped(); // Registrar DialogService
...

I repeat the "add security" process... and the error continues. Before this the render worked ok.

Do you need any additional information to support me on this?

No, this is not where the dialog service is registered, this will register the service:

However this should be in the Blazor app, not in the server app if you have WebAssembly.

Hi @fiore2k1,

Please send us the application source code to info@radzen.com. Upload it to some cloud storage service and send us a download link.

For some reason your application is using EF 9.0 which causes the problem in a .NET 8 app. Changing the version of all EF packages to 8.x seems to resolve the problem.
