问题 I have build a Windows 10 UWP cordova application, and are now trying to sign it. I already have a certificate that is used elsewhere (to sign .net assemblies) so I thought I would use the same one for this application signing.

问题 I have a static class in a common project where I have all my property with all my text (for example, all my titles) I want to know how I can bind my TextBlock Text to this value.

I have taken some code from other Stack questions and my dad (A C#
