Windows Phone 8/8.1 – My Location

If you have Windows Phone and would like to be able easily send your location to someone the code below will be helpful.

When reviewing the code you will find that it is functional but lacks a pleasant user interface, as you build this app you can add your own icon(s) and more features.

Icon Sizes:

Sample	Size	Flip and Cycle	Iconic
	Small	159 × 159 pixels	110 × 110 pixels
	Medium	336 × 336 pixels	202 × 202 pixels
	Wide	691 × 336 pixels	N/A

Download NuGet Package: Windows Phone Toolkit

1. In Visual Studio go to File Menu -> New -> Project
2. Select “Windows Phone App” within Visual C# -> Windows Phone
3. Expand Properties in the Solution Explorer and open “WMAppManifest.xml”
   1. Click on the Capabilities tab
   2. Under Capabilities, check “ID_CAP_LOCATION” AND “ID_CAP_MAP”
