Use custom IoC providers

[godrose]

Right now for existing .NET apps I use custom IoC containers like simple container, autofac, unity, etc.
How does this scenario work in Maui bootstrapping pipeline?

There are two steps to this. You can check out Prism.Maui for an example of how to do this.

The first thing you need is to implement IServiceProviderFactory<T> which you can probably get as a support package from containers that work with AspNetCore already. The second thing you need is to call the UseServiceProviderFactory on the builder. For reference here is the code that we use for Prism.Maui to accomplish this.

builder.UseMauiApp<T>()
       .UseServiceProviderFactory(new PrismServiceProviderFactory(options.Container));


public class PrismServiceProviderFactory : IServiceProviderFactory<IContainerExtension>    
{
    private IContainerExtension _container { get; }
    public PrismServiceProviderFactory(IContainerExtension container)
    {
        _container = container;
    }

    public IContainerExtension CreateBuilder(IServiceCollection services)
    {
       _container.Populate(services); 
       return _container;
    }

    public IServiceProvider CreateServiceProvider(IContainerExtension containerExtension)
    {
        return containerExtension.CreateServiceProvider();
    }    
}
