AppDomains and shared Threadpool?

12 Feb 2007 3:23 AM

Greetings,

I have an application that must load various modules. Each module must be
able to execute concurrently, so I'm spawning a thread and each thread hosts
its own AppDomain. I for various reasons, I must create a custom
threadpool. I would like to share that threadpool with each of the
AppDomains so the threads can be used/recycled between the AppDomains and
the threadpool can continue to be controlled/scheduled by the default
AppDomain/Process.

Is there a way to share the threadpool between each AppDomain? I'm hoping
this can be a pure C# solution. Ultimately, it is a Windows Service that
will load other modules that act as a service and function independantly.

Thanks,
Shawn

Shawn,

You might consider Microsoft's Concurrency and Coordination Runtime
(CCR) or William Stacey's Port Concurrency Runtime (PCR).

CCR looks awesome but unfortunately our company will not license it for our
own internal use so it is immediately out of the question. I'll take a
closer look at PCR.

Thanks,

Shawn,

And one disadvantage of the CCR is that you have to download the 45 MB
Robotics Studio. Honestly, I haven't used either one yet so I can't
comment too much on their capabilities.
