My C# Project Connect to ocsp.verising.com

[C# Programming]

Hi , have a good day ,

I build a new Windows C# Application With Visual Studio ...

And when ever I run it , it's try to create connecting with this site ocsp.verising.com ,

I discover this hidden connection by "ESET Smart Security firewall"

I thought may be Microsoft , trying to steal my code , and sell it in the black market ?

P.S: I wrote this Application Piece by Piece , and there are Nothing like networks coding ,
or any things related to the internet , or to this site ocsp.verising.com


Thank in advance
I know nothing , I know nothing ...
