MarshalByRefObject

MarshalByRefObject is a programming concept in .NET that allows objects to be accessed across different application domains without copying them. Instead of sending the entire object over the network or between processes, it provides a reference to the object that resides in its original location. This approach improves efficiency and ensures that changes made to the object are consistent, as all references point to the same instance. It's useful in distributed applications where components need to communicate and interact with objects remotely while maintaining data integrity.
