Adaptive Tile Extensions is a project to more easily allow a developer to create the xml required for adaptive extensions in Windows 10.
Information on what they are can be found in the Build 2015 talk about Tiles, Notifications and the Action Centre https://channel9.msdn.com/Events/Build/2015/2-762
var tile = AdaptiveTile.CreateTile();
var binding = TileBinding.Create(TemplateType.TileWide);
binding.Branding = Branding.None;
var header = new Text("You have mail") {Style = TextStyle.Body};
var content = new Text("Someone likes you!") {Style = TextStyle.Caption};
var logo = new TileImage(ImagePlacement.Inline)
{
Source = "http://fc02.deviantart.net/fs71/i/2013/359/a/4/deadpool_logo_1_fill_by_mr_droy-d5q6y5u.png"
};
var logoSubGroup = new SubGroup {Width = 40};
logoSubGroup.AddImage(logo);
var subgroup = new SubGroup();
subgroup.AddText(header);
subgroup.AddText(content);
binding.Add(logoSubGroup);
binding.Add(subgroup);
tile.Tiles.Add(binding);
var notification = tile.GetNotification();

This helper is a quick and easy way for you to create all the information for a tile, for whatever size you want to support, without having to deal with generating the XML yourself.
