InvalidOperationException: No service for type 'Piranha.AspNetCore.Services.IApplicationService' has been registered

Question

Im trying to use https://piranhacms.org/ template but instead of using SQL Lite I have switched my project to SQL Server when I run the manager(ADMIN) page I have no problems. I can even use the admin to add data to my DB. The error only accures when I am just a normal user trying to access the site. If any one knows why this is happening or thoughts on what I could look into being the problem I would be every greatful.

I set up the datatbase using these insturctions https://piranhacms.org/docs/master/basics/database-setup

My start up file setting up my server

options.UseEF<SQLServerDb>(db =>
            db.UseSqlServer(_config.GetConnectionString("piranha")));
            options.UseIdentityWithSeed<IdentitySQLServerDb>(db =>
            db.UseSqlServer(_config.GetConnectionString("piranha")))

The user page that loads displayes this error.

Answer 1

Add services.AddScoped<IApplicationService, ApplicationService>(); to ConfigurSerices in your startup.cs

Your program search for IApplicationService. That means if you want use an abstraction in your program, you must resolve this abstract object.

There is many ways to resolve it. You can create an object of IApplicationService like answer below. Or you can use a middleware to resolve it.

For ASP.NET Core Dotnet version 6:

builder.Services.AddScoped<IApplicationService, ApplicationService>();

For other versions, you can accept @martijn-takken answer.

If you want more detail on this look at here: https://docs.abp.io/en/abp/4.4/Application-Services

Answer 3

.NET Core supports the dependency injection design pattern. This technique help achieving Inversion of Control between the classes and their relative dependencies.

So, you need to register the IApplicationService service with the concrete type ApplicationService. The AddScoped method will register the service with a scoped lifetime (which is the lifetime of a single request)

builder.Services.AddScoped<IApplicationService, ApplicationService>();
