DryIoc

DryIoc outperforms competitors like Autofac and Grace in benchmarks, with up to 27x faster hot-run and 5x faster cold-start times, and lower memory allocation, as shown in the README's detailed metrics.

It supports advanced DI patterns such as open generics, decorators, wrappers (e.g., Lazy, Func, collections), and conditional registrations, enabling management of complex object graphs.

With over 2000 test cases, thread-safe lock-free operations, and built-in cycle detection, DryIoc ensures robust error handling and stable service resolution in multi-threaded environments.

It targets multiple .NET versions from Framework 4.5 to .NET 9 and offers interpretation mode for platforms like Xamarin iOS where System.Reflection.Emit is unavailable, ensuring broad compatibility.
