An Effect may define several EffectTechniques for rendering objects. An EffectTechniqueBinding provides the logic that selects the appropriate technique when rendering a specific object.

This base class always chooses the first technique of an effect and ignores other techniques. Derived EffectTechniqueBinding class should implement more useful strategies.

Once a technique is selected, the method GetPassBinding(EffectTechnique, RenderContext) can be called. This methods returns an EffectPassBinding. The EffectPassBinding can be used to iterate over all effect passes that need to be applied for the current object.

Cloning:
EffectTechniqueBindings need to be cloneable. The method Clone calls CreateInstanceCore and CloneCore(EffectTechniqueBinding) which are responsible for creating a clone of the current instance. Classes that derive from EffectTechniqueBinding need to provide the implementation for CreateInstanceCore and override CloneCore(EffectTechniqueBinding) if necessary.
