x:String Error

Question

Hi,

Why do I keep getting the below error when I add this simple x:String line:

<x:String x:Key="IconHome">&#xf015;</x:String>

and everything works fine when I remove it. Here is the error:

You asked this same question a couple of months ago I believe here. You were given an answer and that answer linked to a GitHub issue related to the problem. Please continue to use that discussion (or a new one) in Github to resolve your issue since it is still happening.
