It is time for me to write a series of blog items on writing XAML applications for Windows 8. I plan to write one every two weeks. I hope I can keep up the promise.
Custom Fonts
I have developed XAML applications in Silverlight (Browser and Phone) for a couple of years. I used custom fonts in those Apps using Expression Blend. It contains a Font Manager which you can use to embed a font into the application (project/assembly). Blend for Visual Studio doesn’t allow you to use the Font Manager. The menu option is disabled in this Release Candidate. I hope to get it back in a future version.
