Hi,

I have written one c#.net WCF Service, in that Dataset1 contains Master data, i am using this data in the entire service, if someone changes the Master data from outside, i am not able to find that.

for that everytime i am accessing the master data.

Can you please tell me, is there any technique to know in the service, when database change happens automatically?

Thanks in advance.
