Recently, whilst developing Sweepy Cleaner I found that it was a bit of a pain to get the theme colour of the phone in XNA, Microsofts Game Development API. This was frustrating, especially compared to how easy Microsoft have made it for Silverlight Applications. My solution to this issue is WindowsPhoneTheme.dll, a simple to set up, simple to use library which does what it says on the tin.
