Add a proggramming language(J#)and/or(J++)

hello,
I would like to add J# and J++ to Unity
J# especially is very close to C#, both are in .NET
I have been able to create a j# file in windows explorer and it showed up in unity with the logo, but you cannot add it as a script. How can I add J#? And make it count as a script?

Thanks, Asbestosstar

Unity supports C#. UnityScript and Boo are technically there, but I wouldn’t recommend them due to lack of active support. Those are the only languages supported.

Does it derive from MonoBehaviour?
