Screenshot: wrong culture name

In Mono 2.10, System.Globalization.CultureInfo.CurrentCulture returns culture name "en-US" under German Windows.

Steps to reproduce:
* German Version of Microsoft Windows
* Mono 2.6 and Mono 2.10 installed
* run csharp in Mono Command Prompt (each version)
* execute following command: System.Globalization.CultureInfo.CurrentCulture;

Actual result:
* Mono 2.6 returns culture name "de-DE"
* Mono 2.10 returns culture name "en-US"

Expected result:
* Since it is a German version of Microsoft Windows, Mono 2.10.8 should return "de-DE" too

The issue was tested with Mono 2.6.7 and Mono 2.10.8. (see attachment)

This seems not to be an issue under Linux (tested with Mono 2.10.5 under Ubuntu Oneiric).
Comment 2 Thomas Klose 2012-08-24 10:49:47 UTC
