The fake errors in XAML-how to fix "the attached property 'viewnodeid' was

When developing Windows Store app, sometimes a lot of "the attached property 'viewnodeid' was not found in type 'dependencyobject'." errors in some XAML files.

How to fix these errors?

The solution in a word: The above errors are not the root errors, you can look through all errors in "Error List" and fix other errors. rebuild and the 'viewnodeid' error will disappear. if not, try to reopen the solution.

Similar errors have also been encountered in the past. However, today, we can see that so many 'viewnodeid' errors are messy, and we didn't want to see the Error List. When I searched again, many people were also depressed about this problem, and some of them hit the desk with their heads (after spending come time banging my head off the desk ). Note: If this problem persists when other types of errors are solved, close Vs and re-open the project.
