Why does sending via a UdpClient cause subsequent receiving to fail? Why are standard frequentist hypotheses so uninteresting? An ILoggerFactory instance can be Support for other containers is provided using each specific container's extensions to work with IServiceCollection and IServiceProvider.

Custom IGraphQLBuilder extension methods typically rely on the Services property of the builder in order to register services property to resolve types via the scoped service provider. Only difference is IServiceProvider and IScopedServiceFactory is lifetime, one is Scoped and another one is Singleton. thanks for answer, but if i have many entities i need to rewrite constructors, and can't using Activator.CreateInstance, using injection in method arguments looks ugly, can u tell me good patern with YAGNI following ?

Did the words "come" and "home" historically rhyme? MassTransit would then be able to use IServiceProvider with Autofac to create scopes, resolve dependencies, etc. In short, IServiceProvider.CreateScope() and IServiceScopeFactory.CreateScope() are identical (in non-scoped context even instances of IServiceProvider and IServiceScopeFactory are identical). I don't think it is a good idea for an entity (or a model) to have access to any service. What is the purpose of IServiceProvider.GetService(Type serviceType)? // Add things to the Autofac ContainerBuilder.
