c# 4.0

Unity Engine
1

If I am not wrong, mono already supports .net framework 4.0, am I right?

Are there plans for Unity to support it as well?

2

depends on what you want to do. Some 4.0 stuff works in unity, the only one i’ve tried so far is optional parameters, which works fine.

3

2.0 as far as I’m aware. Check out which version of mono unity are using.

4

It supports more than 2.0.

pretty much anything green, though not entirely (like winforms/system.drawing/asp.net doesn’t work in unity for obvious reasons)

5

It’s approximately 3.5.

I feel stupid for asking this, but when it comes to supporting .net 4.0 is it just a mono problem or does the problem deal with Unity itself not supporting the .net 4.0 framework?

7

it is not stupid I wondered the same. If Unity uses the jit generated code as it is or it need to convert it. In the first case they could update mono easily.
Anyway I needed the new System.threading.Task that are not supported.

8

In our case we like the new GC that mono offers. Hopefully it performs a lot faster than the current GC.

So Unity itself supports C# 4.0? It’s the built-in mono environment that can’t? Am I understanding this right? If Unity can handle C# 4.0 than I was going to get a Visual C# 4.0 book.

Unity uses Mono 2.6 iirc. Mono 2.6 supports large parts of 3.5 framework (FRAMEWORK) and most language features from C# 3.5 and 4.

Mono 2.8/2.10 has greater support for of 4.0 Framework Library and a new garbage collection. But the C# 4.0 book should be fair enough, you won’t be able to use all of that stuff in Unity, but that’s also true for C# 3.5, 3.0 etc. books.

WF, WPF and WCF for example are not implemented in Mono or are not planed etc. So there should be nothing to stop you getting the C# 4.0 book, as its quite unlikely that you’ll need most of the 4.0 specific stuff in Unity anyway.

Thank you. Unity isn’t the only thing I want to use C# for. I want to make apps eventually.
