POCO

POCO stands for "Plain Old CLR Object" or "Plain Old C# Object." It refers to a simple object in .NET that is not bound by any framework-specific requirements. POCOs are typically used in data modeling and are characterized by being lightweight, having no dependencies on external libraries, and not implementing any specific interface or inheriting from a base class that is framework-centric. This design allows developers to create clean and straightforward business objects that can be easily maintained, tested, and utilized in various contexts without the overhead of additional frameworks. POCOs are often employed in Object-Relational Mapping (ORM) systems, such as Entity Framework, where they serve as representations of database entities. The use of POCOs promotes a separation of concerns and enhances the portability of code, allowing for easier integration with different layers of an application.
