C# export

Because Stencyl 3 uses HAXE now, can it export to C#, so I can test it on PS vita?

I'm not sure if the Vita detects the same keystrokes/touches as ios or PC.  It's also possible you'd need to buy a Developer License like you do with Apple.  Also, Stencyl 2.2 is the highest free version of Stencyl at the moment.

Actually the PS Vita can detect touches normally as IOS(I assume) , and he'd need to buy PS Vita dev kit not just license , or become a PS Mobile licensed developer (you can sign up for free and receive the SDK )
but the question he asked was "can it export to C#?"
because the SDK work with C# only , if I'm not mistaken

No, you can't export to C# using Stencyl.
