Port of TagLib to UWP WinRT component. Uses WinRT's new file IO API to work with the sandboxed app model. Right now, only basic tag data is exposed (Album, Artist, Genre, Title, Track number, Year).

IStorageFile file = GetFromWherever();
//Read tag from file
//IO operations are done synchronously, never use TagManager from the UI thread.
var fileInfo = await Task.Run(() => TagManager.ReadFile(file));
var tag = fileInfo.Tag;
string Album = tag.Album; //And so forth for other tag data
//Modify and save tags
tag.Album = "NewAlbum";
await Task.Run(() => TagManager.WriteFile(file, tag));
