How to add all registered services from Blazor to Simple Injector?

Question

I have a server side blazor application and I'm also using simple injector for other dependency injections in my application.

I want to register all services from blazor to the simple injector container because otherwise I will have to duplicate all service registration but also the main problem is that there's some services registrations that I don't know what is the correct way of registering (usually comes from some dependency injection extension library).

For example, I need something like

public void ConfigureServices(IServiceCollection services)
{
    // multiple service registration
    services.RegisterSomeServices();
    // ... 

    // some how register all services into simple injector container
    container.SomeHowRegisterServices();
}

How can I get all registered services from blazor and register in the simple injector container?

There are some discussions on integration, but at the time of writing, there is still no official guidance on how to properly integrate Simple Injector with Blazor components. — Steven

After some time searching, I found in the docs a ServiceCollection Integration Guide which is a way of integrating third party services into the Simple Injector.

What I need to do according to Cross wiring framework and third-party services is cross wire blazor services into simple injector, so for my case, what I need to do is

public void ConfigureServices(IServiceCollection services)
{
    // multiple service registration
    services.RegisterSomeServices();
    // ... 

    // some how register all services into simple injector container
    IServiceProvider provider = services
        .AddSimpleInjector(simpleInjectorContainer)
        .BuildServiceProvider(validateScopes: true);

    // Ensures framework components are cross wired.
    provider.UseSimpleInjector(simpleInjectorContainer);
}
