Does unity support c# 5.0?

as title.

 

No

 

Unity only supports a Mono version of C# for compatibility across different platforms and OS. The highest "equivelant" version to C# mono currently supports inside unity is 2.0. I hope this makes sense!

 

Auntie google knows the exact answer

http://lmgtfy.com/?q=unity .net version
http://lmgtfy.com/?q=unity c# version

I am consciously not giving detailed information when using google for one minute would already give the correct answer.

 

then how about .net 4.5?

 

No

 

Mono 2.0, from what I understand, is the equivalent of .NET 3.5, and are fully compatible with each other. For example, Linq is a 3.5 features and works fine in Unity.

 

Quoted because this is still the right answer, including to the followup.

 

I stand corrected, I assumed mono 2.0 = dotNet 2.0, I don't really delve that deep into multi platform specifics since I mostly develop for windows desktops. Useful to know I've been holding back performance optimisations -_- lol

 

".Net 3.5" actually runs on 2.0, it's mostly compiler/language improvements and extensions, not real .Net changes.

.Net 3.5 basically just installs some libraries. .Net 4 is actually the next new version of .Net, and 4.5 has breaking changes so is also a new version.
