ActionResultObjectValueAttribute.cs

Attribute annotated on ActionResult constructor, helper method parameters, and properties to indicate that the parameter or property is used to set the "value" for ActionResult.

Analyzers match this parameter by type name. This allows users to annotate custom results \ custom helpers with a user-defined attribute without having to expose this type.

This attribute is intentionally marked Inherited=false since the analyzer does not walk the inheritance graph.
