This is a simpel extension which will add the Tweet button from the twitter at the end of the post or page in BlogEngine.NET blogs. This extenstion does not have a settings so you will need to edit the code (just two lines)
Edit the Twitter User name
private static string twitterUser = "geekiestnet";
and How you need to show the count (horizondal, vertical or none)
private static string count = "horizondal";
move this tweet.cs to /App_Code/Extensions/ that's all, you can see screen shots below.
