Testing localized string resources can be tricky, especially if you don't speak multiple languages. This extension adds a new context menu to RESX and RESW files in Solution Explorer that will allow you to pseudo Localize your string resources. Viewing the app with pseudo-localized strings makes it easy to spot any text that doesn't come from a resource.
The pseudo localization can also be easily toggled off (if supported) once your testing is complete.
This extension is provided free of charge but will periodically include a message in the output window asking you to support the ongoing development and maintenance of this and other extensions by becoming a sponsor.
