मैं अपने मुख्य परियोजना में seprate पुस्तकालय और XAML कोड में gif animating के लिए इस कोड का उपयोग कर रहा में Gif एनिमेट:WPF
<controls:GifImage GifSource="/project;component/Images/my.gif" Stretch="None" />

लेकिन मैं त्रुटि प्राप्त करें:
The URI prefix is not recognized.
मुझे यकीन नहीं है कि मुझे त्रुटि क्यों मिलती है। क्या कोई कृपया मेरी यह मदद कर सकता है ?
धन्यवाद, लेकिन यह मेरा प्रश्न समाधान नहीं है। – UFO
