What is the difference between immutable and mutable collections in C#?

In C#, mutable collections can be changed after creation, while immutable collections cannot be modified once created.

Can you give me examples of each type?

Sure! An example of a mutable collection is List<T>, while ImmutableList<T> is an example of an immutable collection.

When should I use immutable collections?

Use immutable collections when you want to ensure data integrity and avoid unintended side effects from modifications.

Are there performance differences between them?

Yes, mutable collections can be more efficient for frequent updates, while immutable collections may have overhead due to copying.
