    Hello Ajay,

    There are two general scenarios causing the issue.

    The first is, if the assembly you are holding reference to is incompatible with the current setup of the project due to different versions of .NET.

    Most of the time it will just pop a warning, however if it is referenced in the XAML it will trigger the error described.

    The other reason that can cause it is if you have reference to an assembly while the user control is in the same WPF form. If this is the case, you should currently have a namespace declaration like this:

    xmlns:igWPF="http://schemas.infragistics.com/xaml/wpf;assembly=REFERENCE"

    and remove the assembly reference from it:

    xmlns:igWPF="">schemas.infragistics.com/.../wpf" or 

    xmlns:igWPF="">schemas.infragistics.com/.../wpf;assembly="

    Should you have any further questions, please let me know.

    Sincerely,
    Tihomir Tonev
