I need to understand that the fonts are "rendered in ASP.NET", but they are rendered on the client side, so it all depends on what is installed in the client hosts. You should not assume too much and provide fallback font names, up to the generic names, such as "serif" or "sans-serif". Please see:

Alternatively, you can embed a font with your CSS:
