Visual Studio 2015 Update 2: Object must implement IConvertable

[Chrissteven81]

After updating to VS 2015 U2 I now get a XAML error on my CompareStateTriggers that says "Object must implement IConvertable" on the Value property

[Chrissteven81]

I found that if you add a fallbackvalue the error goes away

I'm also seeing this on an EqualsStateTrigger's Value property.

Is there any update on fixing this?
