> While ABP has no core dependency to any 3rd-party DI provider, it's required to use a provider that supports dynamic proxying and some other advanced features to make some ABP features properly work. Startup templates come with Autofac installed. See [Autofac integration](Autofac-Integration.md) document for more information.
