What are the performance benefits of using immutable collections in C#?

Immutable collections in C# offer several performance benefits, such as thread safety, reduced memory overhead, and improved performance in certain scenarios due to their non-modifiable nature.

Can you explain how thread safety is achieved with immutable collections?

Thread safety is achieved because immutable collections cannot be changed after they are created. This means that multiple threads can read from them without the risk of data corruption or race conditions.

Are there any scenarios where mutable collections might be preferred?

Yes, mutable collections can be preferred in scenarios where frequent updates are necessary, as they can be more efficient for operations that modify the collection frequently.

How do immutable collections impact garbage collection in C#?

Immutable collections can lead to more efficient garbage collection since they can be shared across different parts of the application without creating multiple copies, reducing memory pressure.
