Error in WPF-Xaml Editor, binding is working though

[RambaaZambaa]

Hi,
the following Tooltip-Binding is throwing an xaml-error in visual-studio:

ToolTip="{c:Binding '(myValue>0 ? \'sentence one\' : \'sentence two\')'}"

"markup extension is not properly closed".

It's working fine in the app at runtime though.

How do i fix that?
Thanks!

IntelliSense isn't aware of CalcBinding intrinsics and marks this as invalid syntax. As this library isn't part of the Microsoft-lead C# ecosystem, IntelliSense won't be internally updated to accomodate to this syntax.
