Sample project that shows CurrentCulture on labels

The CurrentCulture property is returning the incorrect value on iOS7.1 devices. If you set the device Language from English to German it will still return a English value. 

I have attached a simple sample project which verifies this behavior.

Steps to reproduce:
1. Grab a device running iOS7.1
2. Go to Settings -> General -> Language & Region -> Language. Change to Deutsch (German)
3. Run the sample code
4. Confirm that the following code is returning "en-US" instead of "de-DE"

> 2. Go to Settings -> General -> Language & Region -> Language. 

That does not sound right. In iOS 7.1 you have:

> Settings -> General -> International -> Language

What you're showing looks like iOS 8.x options.

But I do see


if I run this in a German iOS 7.1 device.

The first two (.net) properties are build from the value returned from iOS' `NSLocale.CurrentLocale`. If iOS returns an incorrect value then the .net values will be wrong.

I'll confirm with an ObjC app but it really looks like an iOS issue.

note: 99% of our bindings are direct mapping to iOS API, i.e. there's no version checks or alterations of results.

2014-12-05 14:36:59.270 culture25112[8246:60b] Language: en_CA <- that's because of how my country, not language is set

I get the same issue with Xcode/ObjC (both using the simulator and on device), i.e. it's an iOS issue. 

Possible workaround:

It seems that only the collation is being set to "de", not the rest of the properties. That could be used as a workaround, i.e. check the collation and then switch the Thread.CurrentThread.CurrentCulture to match.
