• Convert.Net

1. Regular Expression Tester : که جهت تست Regex‌های نوشته شده استفاده میشود.
2. Encoding & Decoding : جهت تبدیل انواع رشته‌های Encoded ویا Decoded به یکدیگر استفاده میشود و از html - url - EScape-js - Base64 - string و ... پشتیبانی میکند.
3. Encryption & Decryption : جهت Encrypt و Decrypt انواع رشته استفاده میشود که از انکریپتورهای معروفی همچون  AES - Rijndael - DES - SHA - TripleDES پشتیبانی میکند.
4. Language Translation : یک دیکشنری Multi Language آنلاین در اختیار شما برای ترجمه متون قرار میدهد.
5. C# & VB.Net Convertor : برای تبدیل کدهای C# به Vb و برعکس استفاده میشود و  طبق تست هایی که روش به شخصه انجام دادم در اکثر موارد بدون خطا تا حدود 90 درصد تبدیلات رو به صورت موفق انجام میده ولی مانند سایر Convertor‌ها با Lambda Expression کمی مشکل دارد.
6.  Xml & Json Browser : برای مشاهده و تبدیل Xml به Json و برعکس بسیار مفید است .. 
   
7. Linq Tester : برای تست کوئری‌های Linq استفاده میشود . (برای استفاده از این امکان باید Roslyne روی سیستم شما نصب باشد)
