What are the modes of garbage collector operation you know?

In C#, the garbage collector (GC) operates in several modes that affect application performance and behavior:

• Workstation — the default mode for desktop applications. Optimized to minimize delays, runs in the background so as not to block the main thread.

• Server — used for high-load server applications. Runs multiple garbage collection threads in parallel, increasing performance by utilizing multi-processor systems.

• Concurrent or Background GC — allows garbage collection to occur concurrently with application execution, reducing pauses.

These modes can be configured through application settings or programmatically to optimize GC operation for specific tasks.
