WPF Error: System.Windows.Baml2006.TypeConverterMarkupExtension' threw an exception.

This was coming after successful compile but while executing the application.. However, after searching, from one post on StackOverFlow I got know that one of the image in my Resource is not in proper uri. That’s what I corrected and it started working fine.

Initially it was:

<Border.Background>             
      <ImageBrush ImageSource="Resources/BG-horizontal.png" />
</Border.Background>

And when changed to following, it started working fine: See highlighted change.

<Border.Background>             
      <ImageBrush ImageSource="../Resources/BG-horizontal.png" />
</Border.Background>
