Exception using .Net SubscriberCallback Example

Hi,

I tried the SubscriberCallback Example for .Net.  When I run the compiled program, it subscribes to the data, sends it to the screen, waits the number of seconds in the Thread.Sleep.  Then when it hits the finally of the try/catch/finally, there is an exception on rc = s_sdk.stop(espError);  When I comment this line out, the exception goes away.

I wanted to use the example as a basis for something I was developing.  To that end, it would be nice if this example worked more like esp_subscribe or like the java example.

VS 2010

ESP 5.1 SP08

Win 7 64 bit

Compiling for 64 bit executable.

Thank you,

David
