Write an iPhone application

Develop an iPhone Shell application using Visual Studio, C# and Xamarin. This will be a basic shell that only has 3 screens: 1) Login Page: User name and password fields are required and login button. Upon clicking login button, a call to a REST service will be made to authenticate the user. Upon successful login the user will be redirected to Dashboard page. REST service to authenticate user does NOT need developed. The service URL to authenticate user will be provided once project is awarded. The REST service will return a UserID as well upon successful login. 2) Dashboard Page: Displays a welcome message in top right corner. Has a menu of options with 2 options: a) Review Data: clicking will take user to the Order page b) Log out: clicking logout will log user out and redirect them back to the Login page NOTE: The Welcome userxxxx message and menu should be present on both the Dashboard page and the Order Page. Developed in a way that is reusable across any page in the site without duplicating 3) Order Page: Will have a list of 27 order numbers, displayed in pages of 10 order numbers per page with the ability to move to the next page or previous page. Order numbers will come from a REST service. REST service to get list of order numbers does NOT need developed and the URL will be provided once project is awarded. To make the call, a User ID will be passed in to the REST service and a list of 27 OrderNumbers and associated OrderNumberIDs will be returned. It is important that only 10 order numbers are visible at a time, so buttons will be required to navigate the user through the pages of page numbers. 27 Order numbers means there will be 3 "pages" of orders. If the service returns 12 order numbers then there should only be 2 "pages" of order numbers
