What is the best .net programming language for artificial intelligence programming? I know that every program has some positive and negative points, and I know maybe .net programming languages are not the best for AI programming.

But I prefer .net programming languages because of my experiences and would like to know for an AI program which one is better, C or C++ or C# and or VB ?

Which one of this languages is faster and more stable when running different queries and for self learning ?

To make a summary, i think C++ is the best for AI programming in .net and also C# can be used in some projects, Python as recommended by others is not an option on my view !

because : 


It's not a complex language itself and for every single move you need to find a library and import it to your project (most of the library are out of date and or not working with new released Python versions) and that's why people say it is an easy language to learn and use ! (If you start to create library yourself, this language could be the hardest language in the world !)
You do not create a program yourself by using those library for every single option on your project (it's just like a Lego game)
I'm not so sure in this, but i think it's a cheap programming language because i couldn't find any good program created by this language !
If you're talking about pure speed, C will get you there if you really know C and operating systems, etc. C++ is nicer in terms of user friendliness, and won't be much slower. I don't know much about VB but I don't see many benefits.

Please clarify at least generally what the AI program is about. It is extremely difficult to answer the generalized question "What programming language is best for AI"? if you know what I mean. (  I vote python :^]  )

To add: Any programming language of those listed is "stable" if you write things correctly, but C++ and its great IDE's will help you to that point much more nicely than C will. C, to fully utilize it's potential, requires much fiddling with delicate and precise systems. It'll go that little bit faster, as the cost of being less stable in the practical, " uh oh, now I need to troubleshoot this" sense.
