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

Immutable collections in C# can lead to better performance in multi-threaded scenarios, as they are inherently thread-safe.

Can you explain how they improve thread safety?

Since immutable collections cannot be modified after creation, they eliminate the need for locks, reducing overhead and complexity.

Are there any downsides to using them?

Yes, the main downside is that they can lead to increased memory usage since each modification creates a new instance.

How do they compare to mutable collections in terms of speed?

In general, mutable collections are faster for frequent updates, but immutable collections excel in read-heavy scenarios.
