Sample code for the 2nd Preview Edition of "Creating Mobile Apps with Xamarin.Forms"
As of February 9, 2015, all projects have been upgraded to Xamarin.Forms 1.3.3.
Consequently, there is now a little difference between the version of TextVariations here and the one in the PDF version of Chapter 7. With version 1.3.3, there is no longer a distinction between text as the content of the Label tags and text as content of the Label.Text tags. In both cases, whitespace at the beginning and end of the text block is trimmed.
As of March 4, 2015, all projects have been upgraded to Xamarin.Forms 1.3.5.
