Hi. I am using Xamarin for creating a new android application. I am very much noob.

I have done some research and I need some assistance. I need to customize their sample product http://xamarin.com/prebuilt/fieldservice. It uses a sql lite database. It also uses a depreciated google maps api (v1) that i need to change to v3. From my understanding, i need to create a webservice from my sql server database to communicate to the android application. I need the application to view and update the sql server database. I have been searching for a sample solution on how to accomplish this and I am coming up empty handed.

So basically I am looking for someone to help me with:

utilize the google maps api v3 and convert the v1 code in the application.

understand how to create a sql server webservice

connect the webservice to the app

update the database with the app

I know its asking a lot, but i am trying to locate the best resources to accomplish my task.

So if someone could help me get started that would be great, and thank you for reading this.
