Senior .Net Developer Interview Question:

Please explain what is immutability, what is it for and how is it codified?

Submitted by: Muhammad

The ability of objects not to change their state, once created, helps improve the maintainability of the code. When a mutable object encapsulates its changes without being explicit in the code, following the flow becomes difficult. The level of difficulty increases in case of multi-threaded applications. To create immutable objects, pass the arguments for their creation in the constructor; make their properties read-only later.
