Mister Goodcat wrote a good article a little while ago about using P/Invoke in Silverlight 5 to display the native font chooser dialog with the ChooseFont function. I couldn’t get the code working for a 64-bit executable, however, as the definition of the CHOOSEFONT structure on MSDN he used as a basis for the managed implementation doesn’t match with what’s in the Windows SDK. I’ve created a page on PInvoke.net for the function that includes a definition of CHOOSEFONT that works in both 32-bit and 64-bit versions of Windows.
