When should I use immutable collections in C#?

When should I use immutable collections in C#?

Immutable collections in C# are useful when you want to ensure that the data cannot be changed after creation, which can help prevent bugs.

Can you give me some examples of when to use them?

Sure! Use immutable collections when you need thread safety, when passing data across different parts of an application, or when you want to maintain a history of changes.

What are the performance implications of using immutable collections?

Immutable collections can have performance overhead due to the need to create new instances for modifications, but they can improve performance in multi-threaded scenarios by avoiding locks.

Are there any specific types of immutable collections in C#?

Yes, C# provides several immutable collections like ImmutableList, ImmutableArray, ImmutableDictionary, and ImmutableHashSet.
