Comentários
Attributes enable programmers to attach custom information to various program entities and retrieve attribute information in a run-time environment. In the runtime, a custom attribute, such as HelpContextAttribute, allows you to use this property to signal and display context-sensitive Help for an application.
The HelpContextAttribute inherits from the attribute class in the Microsoft .NET Framework.
