When declaring some types as volatile e.g. private volatile int i; I get a Predefined type 'System.Runtime.CompilerServices.IsVolatile' is not defined or imported NetDuinoMMC error. Is volatile not allowed in .Net MF or is it not required? If its not available, how to we work around it without doing a full 'lock' on an object?

Hmm, really interesting. We always use monitors (locks) for this--so I've never tested that on .NET MF before. I wonder how hard it would be to create a System.Runtime.CompilerServices.IsVolatile type for .NET MF (much like the method extension class was added by the community). Chris

I think your best bet is the Interlocked. family of operations (CompareExchange, Increment, and the like)

Hi Chris, Can you provide a link to info on the method extension class that I can look at?

Yes these would be better than doing a lock, but I really don't they shouldn't be necessary, just need to disable caching of a couple of variables.

I'll implement it with these for now.

I've got the same problem. I'm trying to do multithreading described http://msdn.microsof...a2f3ay4(v=vs.80).aspx . Can someone explain what to use instead.
