Problem with localization ASP.NET applications: thing to keep in mind

Ever tried to create an localizable ASP.NET 2.0 application?
Seen following links?

It does work very well until you decide to keep only localized resources, for example:

MyPage.aspx.en-US.resx
MyPage.aspx.de-DE.resx
MyPage.aspx.ru-RU.resx

Once you delete the default resource MyPage.aspx.resx - the localization stops to work!

So here is the rule:

NEVER DELETE DEFAULT RESOURCE FROM PROJECT IF THE APPLICATION MUST BE LOCALIZABLE

and enjoy...
