Are there any limitations on the number of threads that can be launched on a single process?

In .NET, there is no hard limit on the number of threads that can be created within a single process. However, in practice, the number of threads is limited by system resources: available memory, CPU capabilities, and operating system restrictions.

Each thread requires a stack allocation (by default about 1 MB), so creating a very large number of threads can quickly exhaust memory. Additionally, too many threads lead to overhead from context switching and decreased performance.

Therefore, it is recommended to use a thread pool (ThreadPool) or asynchronous models to efficiently manage the number of concurrently active threads.
