RESX workflow
Translation example
A .NET RESX resource file, English to Spanish
A five-entry resource file written for this page: titles, a string with a {0} placeholder, a confirmation with quotes and a picture reference that is not text. Keys, comments and the file reference stay; the strings are translated.
