Question

I have

<Image x:Name="imgScreenshoot" Margin="2" Source="{Binding Converter={StaticResource ImageConverter1}}" />

within a ResourceDictionary

at the same time it has

<local:ImageConverter x:Key="ImageConverter1" />

In design mode there is no error.

But when I start application I got the error that app. canot resolve reference ImageConverter1.

How do I can fix it? Thank you!

Declare the converter higher up, before it is used.
