There is standard multilanguage support in WinForms (as well in WebForms).
Here you may find links to articles on the subject:
In general, for WinForms application you have to set Localizable
property of the form to true
and the Language
property to the language you wish ("Polish
" should be in the drop-down for that property).
Note that new controls can be added only for forms with Language
set to "(Default)
". So, first you have to add the controls in the form and after that to set the language.
