Visual Studio 2010: why all the foreign language folders?

Question

In the /bin/debug folder of my solution I've noticed a slew of what appear to be foreign language folders with names like "ar", "bg", "ca", "cs", "da"... all the way to "zh-Hant". The folders each have copies of these 4 DLLs:

• System.ComponentModel.DataAnnotations.resources.dll
• System.Windows.Controls.Data.Input.resources.dll
• System.Windows.Controls.Data.resources.dll
• System.Windows.Controls.resources.dll

The Silverlight application I'm developing doesn't have any internationalization support, so I can't figure out how these files and folders got there. All in all, it's almost 13 MB of files.

Worse yet, when I delete them, they are regenerated the next time I build the solution.

Any advice?

ETA:

Here's the list of DLLs referenced by the Silverlight project:

• ESRI.ArcGIS.Client
• ESRI.ArcGIS.Client.Toolkit
• mscorlib
• system
• System.Core
• System.Net
• System.Runtime.Serialization
• System.ServiceModel
• System.Windows
• System.Windows.Browser
• System.Windows.Controls
• System.Windows.Controls.Layout.Toolkit
• System.Windows.Controls.Navigation
• System.Windows.Interactivity
• System.Xml

I've noticed that some referenced assemblies tend to use localized resources for internationalization, for example Castle ActiveRecord. I just checked with a project I'm working on (that uses Castle ActiveRecord and ZedGraph - both of which have localized resources in separate assemblies), and after building, the language folders were recreated in my bin folder.

So imo, I believe you're referencing a similar assembly in your project that has localized resources, possibly the Silverlight assemblies or the ArcGIS assemblies (never worked with either).
