Localize strings in XAML UI in UWP

Question

I have a resource entry named info_278 in the Resources.resw file on my UWP app. I have 3 scenarios where I need to use this resource but looks like I need to duplicate this to cater to different scenarios. Scenarios are as follows.

1. Error message content from code

   var displayErrorOnPopup = ResourceHandler.Get("info_278");

2. TextBlock Text property from XAML (Looks like a new entry needed as info_278.Text)

   <TextBlock x:Uid="info_278" Margin="10,0,0,0" />

3. Button Content property from XAML (Looks like a new entry needed as info_278.Content)

   <Button x:Uid="info_278" Margin="10,0,0,0" />

How do I proceed without duplicating this resource in the .resw file?

The only way to avoid duplication is to set the string value in code-behind using ResourceLoader. Because you could direct access to the specific property of the target control. Like this:

var resourceLoader = Windows.ApplicationModel.Resources.ResourceLoader.GetForCurrentView();
this.TextBlock.Text = resourceLoader.GetString("info_278");

If you are not going to do it in the code behind, then I have to say there is no way to avoid the duplication of the resource string. You should add info_278.Text and info_278.Content for different XAML scenarios.
