LifestyleCreateHybrid Method (FuncBoolean, ScopedLifestyle, ScopedLifestyle)

Simple Injector
The hybrid lifestyle allows mixing two lifestyles in a single registration. Based on the supplied lifestyleSelector delegate the hybrid lifestyle will redirect the creation of the instance to the correct lifestyle. The result of the lifestyleSelector delegate will not be cached; it is invoked each time an instance is requested or injected. By nesting hybrid lifestyles, any number of lifestyles can be mixed.
