  • Hi,

    In my silverlight 4 application designer view show following error.

    System.Reflection.TargetInvocationException

    Exception has been thrown by the target of an invocation.

    System.InvalidOperationException

    An unhandled exception was encountered while trying to render the current silverlight project on the design surface. To diagnose this failure, please try to run the project in a regular browser using the silverlight developer runtime.

  • Hi,

    Would you mind post XAML on here.

    Did you deal with any class that can not instantiate in XAML.

    Regards

  • Are you using any third party control? Does this error occur when your page/control is empty?
