3. What are attributes?
Attributes are keyword-like declarative descriptions that provide useful metadata for methods, properties, and other fields within your classes. When your code is compiled, these descriptions are discoverable through reflection and provides the user of the class with other helpful information. Attributes can be applied at the class and assembly level.
