Changelog

3.0.0 — 2026-10-13

A ground-up rewrite for .NET 10. The 1.x/2.x codebases (.NET Framework 4.0/4.7.2, .NET Standard 1.0/1.1/2.0, Xamarin iOS, OWIN) were removed.

Added

• Drop-in IServiceProvider for Microsoft.Extensions.DependencyInjection and ASP.NET Core: YoctoServiceProviderFactory, BuildYoctoServiceProvider, Populate. Passes all 143 tests in Microsoft.Extensions.DependencyInjection.Specification.Tests 10.0.
• Scoped lifetime (AsScoped, RegisterScoped) and IServiceScopeFactory.
• Keyed services, including [FromKeyedServices], [ServiceKey], and KeyedService.AnyKey.
• Open generic registrations.
• IEnumerable<T> constructor injection.
• IAsyncDisposable support and DisposeAsync. Instances are disposed in reverse creation order.
• Validate() and ValidateOnBuild to detect missing, ambiguous, circular, and captive dependencies.
• Runtime circular-dependency detection.
• IModule and RegisterModule.
• Unregister and IRegistration.Remove.
• Native AOT and trimming annotations (IsAotCompatible).
• yocto.Wpf package with {yocto:Resolve {x:Type …}}.

Changed

• The namespace is now Yocto (was yocto).
• new Container() is public. Child containers are IContainer.
• The greediest constructor satisfiable from the registration’s container wins, and is selected again after registrations change. Registration order no longer matters.
• Lifetimes are configured with WithLifetime(name, options). Constants moved from Instancing to Lifetimes. ILifetimeFactory and IInstanceFactory were redesigned around LifetimeContext.
• RegisterEnumerable replaces AsEnumerable. Enumerables are stored per container instead of in a static dictionary.
• RegisterInstance no longer disposes the instance.
• Application.Push/Pop are static, and Application.Current follows them.
• RegisterAssembly passes the target container to AssemblyRegistration.Initialize (2.x always passed Application.Current).
• Failures throw InvalidOperationException instead of Exception.

Removed

• Targets other than .NET 10, and their compatibility shims.
• yocto.owin (an unimplemented stub).
• ResolveResourceExtension (name-based lookup). Use yocto.Wpf’s ResolveExtension.
