The type or namespace name 'UI2DSprite' could not be found (ARM)

[cygnus]

Everything works fine when vuilding my project against a desktop target, however we want the project to be launched from within the Windows Store.
Building the project (Visual Studio 2013 project) againt the ARM target, following issue does pop up, preventing the project from building:

1. Error   1       The type or namespace name 'UI2DSprite' could not be found (are you missing a using directive or an assembly reference?)        F:\Unity 4\Chess\Unity\Assets\NGUI\Scripts\Interaction\UIButton.cs      78      25      Assembly-CSharp-metro-vs2013

I'm using the latest NGUI 3.6.3 (yes, I completely removed the previous version of NGUI and no other asset is dependent on NGUI, so no lite versions etc are in the project) and Unity 4.5.0f6.
Looking at the project within Unity I see the file UI2DSprite is present and has the following preconditions specified:

1. #if !UNITY_3_5 && !UNITY_4_0 && !UNITY_4_1 && !UNITY_4_2

This would mean the UI2DSprite class should be included into the visual studio project and it is, as I can locate it under Assembly-CSharp-metro-vs2013 (Windows 8.1)\Assets\NGUI\Scripts\UI.
For some reason the class isn't picked up though.

Anyone any idea on how to resolve this?

Solved it by removing the

1. #if !UNITY_3_5 && !UNITY_4_0 && !UNITY_4_1 && !UNITY_4_2

predefines as I'm running Unity 4.5. Something must be wrong with this check though

Could be that one of those are defined somewhere as a left over from the older editor? Try in Visual to do a check for it by just typing them out, then you'll see if they're defined.

It can be defined either in the build settiings or in an external file that I can't remember the name of.

I am seeing the exact same thing, on x86. I replace the faulty preprocessor symbols "UNITY_4_0_0" and "UNITY_4_0" with "UNITY_4_5_0" and "UNITY_4_5". This works, until I have to make another build. After every build, the Preprocessor symbols get changed back to the same bad values. I don't see how this could be left over from an old editor. I am not sure if I every had Unity 4.0.0 on this box, if I did it was several months and many upgrades ago.

I would like to find a better solution than ripping out all the code that screws up because of the bad preprocessor symbol.

Try Assets -> Sync MonoDevelop Project

This post is about building a Windows Store App, which requires Visual Studio. I am having problems with the symbols produced for the Visual Studio build. Sync the MonoDevelop project has no effect.

Then try building again. The WSA solution is created by Unity when you build. If this doesn't solve it, then I suggest reporting a bug to Unity. WSA/WP8 support is still in beta stage judging by all the bugs.
