Hi All,

Recently I update my OS from windows 8.1 to windows 10. After completing the Visual studio 2015 professional update 3. When I lunch the my WPF application I found that XAML design forms are not loading and I am getting below SDK exceptions.

“System.InvalidOperationException

The Windows Software Development Kit (SDK) required by the XAML Designer was not correctly installed. Consider repairing your installation of either Visual Studio or the Windows SDK.

I did following steps to resolve this issue. But the issue is not resolved.

Link 1: System.InvalidOperationException The Windows Software Development Kit (SDK) required by the XAML Designer was not correctly installed.

As per above link I updated the Visual Studio's tools and updating the Windows SDK to the Windows 10 no use issue remains same.

Link 2: social.msdn.microsoft.com/Forums/vstudio/en-US/4aaebcb3-cae9-45f6-8a80-6dcba6ca459b/xaml-editor-error?forum=visualstudiogeneral

As per the above link source performed the below actions to resolve the issue. But no use.

Action 1:

Again format the laptop and reinstalled the windows 10. Then download the Visual studio 2015 professional update 3 from official MSDN site and installed. ---- No use the issue same.

Action 2: Updated all the installed Windows SDK kit --- No use the issue is remains same.



Action 3: Updated the windows update’s also.



Action 4:
