Upvoted. I am delighted to read a post from you with on-topic content :) Seriously, I think it would be very valuable for CodeProject to have an article on this. thanks, Bill «... thank the gods that they have made you superior to those events which they have not placed within your own control, rendered you accountable for that only which is within you own control For what, then, have they made you responsible? For that which is alone in your own power—a right use of things as they appear.» Discourses of Epictetus Book I:12

WPF styles "cascade"; from the application level; through to local assignments; down to the property level. By refraining from setting any styles at a "low" level, you can influence the entire "theme" of an app by only (first) setting styles at the "application level", which will then cascade down to the lowest level. e.g. Define the style of a "TextBox" at the app level, and the entire app will have a similar textbox style; while still being able to override at any level in the "visual tree" (of ui controls). By limiting the setting of "background" and "forground" colors to "dynamic resources" (versus "static" resources) at the app level, I can give the user the ability to change theme colors on-the-fly from "summer" to "winter" (for example).

To me, "some" means one, all, or anything in between :) In this case, you plan for any number. (I think when I did have a "test" environment, I would change the entire background if there was any chance there would be any confusion).

Ask them "why" they are using MVVM. (Most people can't). The answer (or lack of one) will tell you volumes about what drives the "standards" people in your organization. "(I) am amazed to see myself here rather than there ... now rather than then". ― Blaise Pascal

If you believe the news, "programming", in terms of quality of life, has exceeded dental and other medical vocations as a preference. Certainly if you can work remotely. I have also found (almost) no "age" discrimination working remote versus "local". (Only do "voice interviews" tho ... tell them "video chats" are for voyeurs).
