 Smart.Resolver .NET is simplified resolver library, degradation version of Ninject.
 
+* ASP.NET Core / Generic Host support
+* Xamarin support (Code generation mode and Reflection mode both supported)
+* Transient, Singleton, Container(child) and custom scope supported
+* Callback, Constant provider supported
+* Property injection supported (optional)
+* Custom initialize processor supported
+* Construct with parameter supported
+* Constraint supported (like named)
+* Missing handler supported (For automatic registration, Xamarin integration, open generic type, ...)
+* Customization-first implementation, but not too late (see benchmark)
