x:TypeArguments now works like all other XAML type references
I got an internal question about x:TypeArguments syntax as somebody was migrating an old PageFunction example to RC1.
x:TypeArguments used to blindly make “Object” work. It would just paste it into the .g.cs file via the codedom. It worked because there happened to be a using statement for System.
We now require the same type syntax that you would need to refer to any type inside of an objectelement.
Since you must qualify <Object> as <sys:Object /> as shown here:
<sys:Object xmlns:sys="clr-namepsace:System;assembly=mscorlib" />
Thus you must use sys:Object inside the value of x:TypeArguments as well:
