VContainer#
The extra fast DI (Dependency Injection) for Unity Game Engine. "V" means making Unity's initial "U" more thinner and solid..!
- Fast Resolve: Basically 5-10x faster than Zenject.
- Minimum GC Allocation: In Resolve, we have zero allocation without spawned instances.
- Small code size: Few internal types and few .callvirt.
- Assisting correct DI way: Provides simple and transparent API, and carefully select features. This prevents the DI declaration from becoming overly complex.
- Immutable Container: Thread safety and robustness.
Features#
- Constructor Injection / Method Injection / Property & Field Injection
- Dispatch own PlayerLoopSystem
- Flexible scoping
- Application can freely create nested Lifetime Scope with any async way for you like.
- Pre IL Code generation optimization mode
- ECS Integration beta
DI + Inversion of Control for Unity#
DI containers we can make pure C # classes the entry point (not MonoBehaviour). This means that the control flow and other domain logic can be separated from the function of MonoBehaviour as a view component.

- By default, both VContainer and Zenject use reflection at runtime.
- "VContainer (CodeGen)" means optimization feature by pre-generation IL code of Inject methods by ILPostProcessor. See Optimization section more information.
