If you want to read a file from your project you can for example do it like this:

string fileContent;
StorageFile file = await StorageFile.GetFileFromApplicationUriAsync(new Uri(@"ms-appx:///example.txt"));
using (StreamReader sRead = new StreamReader(await file.OpenStreamForReadAsync()))
fileContent = await sRead.ReadToEndAsync();

Also please ensure that you have set the Build Action of your file as Content (it should be as default).

More about URI schemes you will find here at MSDN.

A slightly different way to access the file:

var folder = Windows.ApplicationModel.Package.Current.InstalledLocation;
var file = await folder.GetFileAsync("sample.txt");
var contents = await Windows.Storage.FileIO.ReadTextAsync(file);

It can only run in Windows Phone 8.1. No previous version of windows phone (Windows Phone 8, Windows Phone 7) would be able to run your app.
