So I've tried following this official Microsoft Localization Guide but I get a runtime FileNotFoundException which is thrown from the designer file whenever I try to use anything in it. My resx file is name "AppResources.resx", the designer file is generated correctly as far as I can tell. We've looked around a bit and we think the error might have to do with the namespace. Our current namespace for the app resources class is as such "CompanyName.SharedProject.AppResources.resources" according to reflection. The directory structure is SharedProject/AppResources.resx/AppResources.Designer.cs. Any help would be appreciated!
