Question

I’m looking for a good library, preferably in C#, which I can use in a windows service and it will handle all the multithreading functionality needed.

The service will run every x minutes, check a database for processes to call, and for each of them spawn a thread and run it.

Each thread should handle exceptions, logging and such.

Any suggestions?

Project Description

Smart Thread Pool is a thread pool written in C#. It is far more advanced than the .NET built-in thread pool.
Here is a list of the thread pool features:

• The number of threads dynamically changes according to the workload on the threads in the pool.
• Work items can return a value.
• A work item can be cancelled.
• The caller thread’s context is used when the work item is executed (limited).
• Usage of minimum number of Win32 event handles, so the handle count of the application won’t explode.
• The caller can wait for multiple or all the work items to complete.
• Work item can have a PostExecute callback, which is called as soon the work item is completed.
• The state object, that accompanies the work item, can be disposed automatically.
• Work item exceptions are sent back to the caller.
• Work items have priority.
• Work items group.
• The caller can suspend the start of a thread pool and work items group.
• Threads have priority.
• Can run COM objects that have single threaded apartment.
• Support Action and Func delegates.
• Support for WindowsCE (limited)
• The MaxThreads and MinThreads can be changed at run time.
• Cancel behavior is imporved.
