What is Rystem?

Get Started with Runtime Dependency Injection

Adding runtime provider

builder.Services.AddRuntimeServiceProvider();

and after the build use the runtime provider

var app = builder.Build(); app.UseRuntimeServiceProvider();

Add service at runtime

await RuntimeServiceProvider.GetServiceCollection() .AddSingleton<Service2>() .RebuildAsync();

Add service at runtime with lock

await RuntimeServiceProvider .AddServicesToServiceCollectionWithLock(configureFurtherServices => { configureFurtherServices.AddSingleton(service); }) .RebuildAsync();

Add fallback for Factory and automatic rebuild of service collection

In this example Factorized is a simple class with a few parameters.

services.AddFactory<Factorized>("1"); services.AddActionAsFallbackWithServiceCollectionRebuilding<Factorized>(async x => { //example of retrievieng something await Task.Delay(1); //example of ServiceProvider usage during new service addition var singletonService = x.ServiceProvider.GetService<SingletonService>(); if (singletonService != null) { //example of adding a new service as factory to the service collection. You need to pass a delegate. x.ServiceColletionBuilder = (serviceCollection => serviceCollection.AddFactory<Factorized>(x.Name)); } });
