How to debug XamlParseException in WPF?

Question

Hi,

  I am getting XamlParseException for one of my xamls which reads somethign like this. This xaml is for Usercontrol.

"Cannot assign root instance of type <class name of xaml.cs> to <class name of xaml.cs>". And it is showing error occured at Line 0 and Position 0.

I looked at the Debug -> Output window to find some more exceptions but unfortunately I couldn't found any other than the XamlParseException.

Can someone please help me in figuring out the exact issue?

Thanks,
shaba.
