I just read this:“The CCR (and me) does not want its users to think about threads. The CCR user guide should be more explicitbut unless you want tight thread affinity for legacy interop reasons, always assume tasks, including tasks you yield to from an iterator will run on *arbitrary* thread context. You should basically not care what thread executes your task.”Ok,”unless […]”. However, what if we do need tight thread affinity, e.g. throw certain exceptions from the main threa

Hello, I have tried to copy and paste SimulatedLRF service to MySimulatedLRF service. Everything was ok. Then I have tried to copy and paste LaserRangeFinderEntity class from Entities.cs to MyLaserRangeFinderEntity. After all that, I modify some codes in MySimulatedLRF service.public class MySimulatedLRFService : svcbase.DsspServiceBase{simengine.MyLaserRangeFinderEntity _entity;void InsertEntityNotificationHandler(simengine.InsertSimulationEntity ins){_entity = (simengine.MyLaserRang

I am trying to create Erlang-style supervisor trees, where a supervisor is reponsible for monitoring and restarted worker processes. Each worker process has a unique Id that I need to propogate back to the supervior when the worker has an unhandled exception. Is there any way to add do this with causalities? I can only get the exception to the supervisor but no “source worker id”.Any ideas?

Hi,I have been using the July 2008 CTP version of MSRS. I have found that some of my web cameras when used with the latest web cam service throw an error: “Unhandled exception at 0x7e46c2ef in WebcamPipeServer.exe: 0xC0000005: Access violation reading location 0x00000023”. I originally posted this unde the community forum. I tried getting the previous version of the WebCam service to run under the July 2008 CTP. This has led to a whole series of new problems.Is there a work around
