But you should be able to do something.
We provide Arial font embedded in the engine ("Fonts_Arial") but it should work with custom fonts too. To use a custom font, you need to compile a font for XNA (generate an xnb). Unfortunately, the Asset Compiler doesn't have an "font" type, so you need to make a classic XNA project in order to do that.
You could follow the first step described here to generate the font xnb : http://msdn.microsoft.com/en-us/library/bb447673.aspx
Once you have your font XNB, just put it into your application content directory, and use the font name (the xnb filename without .xnb) to display your text.
The asset compiler should support font compilation in release version
