How can i communicate with GPS?

[RiskyHunter]

Hi;

i wanna ask you about the APIs that i can use to connect my application with the GPS which is in the mobile phone;

am thinking about creating an application in the mobile phone that have the ability to communicate with the GPS to extract the current user location, and another application in the server to get the location generated and also asks for the user location each time i need it;

plz help me to get started in this project actually am new with c#;

thanks a lot;
