Realtime threads using .NET CF? Anyone?

[=?ISO-8859-1?Q?Allan_Bo_J=F8rgensen?=]

Is it possible to use the realtime subsystem of CE.NET to make realtime
managed threads? I'd very much like to have code running C# do something
at extremely regular intervals (40 ms, to be precise, and CE.NET will do
this nicely), but my understanding is that this is not supported by the
..NET CF out of the box. Is there any way to make it work anyway? Will
support come in .NET CF 2.0?

I understand the difficulties of using GC and realtime threads at the
same time, but I'd really like this to work. We have a largish
application framework for measuring and control for the standard
framework on WXP(E), and we'd like to port this to .NET CF on CE.NET and
use it for controlling industrial equipment, and use the realtime
features of CE.NET at the same time. Are we asking for too much?

Managed threads themselves are not real-time because of the GS and JITting.
Is it possible to break your application in a real-time part and a not
real-time part? In that case you can write your real-time functionality in
eVC and the rest of it in managed code. You can P/Invoke to collect data
from your real-time functionality. You can take a look at this article for
an idea how to get this working:

Also make sure to stop by for session CEA308 on Thursday July 1st to learn
more about the real-time behavior of the .NETCF.

No going to happen. GC systems are by nature non-deterministic.
