Multilanguage Application

If you want to develope the Multi Language Application with newest Microsoft technology for supporting multi language feature then you can follow below:
New innovations in dot net technologies causes you not to need to add a new form for each language. You can have a form with multi configuration, image, and text … on interface.
Step 1: Insert New Form: Ctrl+Shift+A>WindowsForm
Step 2: Insert New Language: [On Form]RightClick>Properties>Design>Language>Select a new language like(French, Italy, US, Persian and ...)
Step 3: Insert New Language again: more and more...
Step 4: For Changing Languages you can use below

Thread.CurrentThread.CurrentUICulture = new CultureInfo("fr-FR");
Thread.CurrentThread.CurrentUICulture = new CultureInfo("es-ES");
Thread.CurrentThread.CurrentUICulture = new CultureInfo("it-IT");
Thread.CurrentThread.CurrentUICulture = new CultureInfo("en-US");
Thread.CurrentThread.CurrentUICulture = new CultureInfo("fa-IR");

PS: this method is compatible with Microsoft .Net Framework 2.0 Beta 2 Compiler but I think that you can use this for old version and newest version of .net resealed.
