Question

I am trying to use an Icon in my WPF application, and some images for other things, but I keep getting errors from the Designer View saying stuff like “path-x is not a valid resource or cannot be found.” – where “path-x” is the path of whatever image I am trying to use.

If it were looking in the right place, I bet it’d find it 😉

BUT, then, it decided to not give me that error anymore. So, I went ahead and clicked Run (F5), to see my new Icon in the title bar. Only to be confronted with this beast:

“System.Windows.Markup.XamlParseException
occurred Message=’Provide value on

and line position ’50’.

Why is this thing giving me attitude? I’m just trying to insert an image…

Updates

Here is the XAML that was produced for the icon when I tried to add the Icon using the Properties Pane:

<Fluent:RibbonWindow x:Class="One_Stop_Management.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:Fluent="clr-namespace:Fluent;assembly=Fluent"
        Title="One Stop Management" Height="727" Width="1208" Icon="Resources\favicon.ico">

Latest Update

I can’t even add an icon using the properties pane, below is the error it gives me.

I’m sorry I can’t be more helpful. On reading your question at first I thought it’d be just a type mismatch, like where you were specifying a string when it was meant to be an image. The issue seems to be one that has multiple possible resolutions. Instead of listing them all I’ll just link you to the Microsoft Connect page that has them on it.
