Asp.Net

builder.Host.UseServiceProviderFactory(Avalanche.Service.ServiceProviderFactory.Instance) assigns Avalanche.Service as the dependency injection implementation (Avalanche.Service.DependencyInjection.dll).

builder.Host.UseServiceProviderFactory(Avalanche.Service.ServiceProviderFactory.Instance);

builder.Host.ConfigureContainer() allows to assign handlers into IServiceBuilder (see more) and logger decorator example. Handlers can participate in construction of services, decorate, modify, etc them.

builder.Host.ConfigureContainer((HostBuilderContext _, IServiceBuilder sb) =>
{
    // Add handlers
    sb.AddAction((IQuery q) => System.Console.WriteLine(q.Request));
});

Routing attribute [FromServices] injects services, such as IService.

app.MapGet("/", ([FromServices] Avalanche.Service.IService service) =>
{
    // Issue request
    Type type = service.GetRequired<TypeRequest, Type>("System.String");

    return Results.Ok("Hello world");
});
