[Mono-osx] Mono - WCF

[Sheen Chandy]

Hi,

Thanks for you reply.

I tried with changing instance-context and still it is taking long
time to get called.
Actually i required concurrency here (that is why i used
InstanceContextMode.PerCall). When first function
(LongRunningFunction()) is running I need to call my second function
(StopLongRunningFunction()).
I am sorry i made one mistake in my sample code, the 'Thread' i am
creating in LongRunningFunction() is actually a static one so that
every instance can access that thread.

Thanks &  Regards
Sheen
