.NET BinaryFormatter

The .NET BinaryFormatter is a tool used in software development to convert complex data, like objects and data structures, into a compact binary form for storage or transmission. When needed, it can restore the data back to its original form. Think of it as a way to save the state of an app so it can be paused and later resumed exactly where it left off. While useful, BinaryFormatter has security concerns and is less recommended for new projects; safer, modern alternatives are preferred for serialization tasks.
