For example, using resharper in C # code, I can refactor "Move to resource" to a string literal. Resharper will move the gated string to the resx file and replace my C # with a link to a strongly typed resource. This is very useful when writing a globalized application. I am looking for a tool with similar functionality, but for xaml.
ReSharper Move to Resource actually supports XAML, but only in WPF projects. Silverlight and WP7 are not currently supported.
