Do we need docs about this detail , like saying after version X you won't need to set |
I don't think the docs currently say that you do need to set |

Description of Change
At the moment, anyone creating a custom control is responsible for explicitly setting the value of
DesiredSizeduring the measure step. This is confusing for implementers - it's not obvious that this is required. And honestly, it's only required because we didn't handle it in theIView.Measure()implementations, which would make a lot more sense than forcing everyone to handle it themselves.These changes set the
DesiredSizevalue to whatever gets returned fromMeasureOverride()(which is what all the implementations were already doing).Issues Fixed
Doesn't fix #7613 exactly, because the issue reported there isn't really a bug. But it does make the creation of custom controls based on ContentView much more intuitive.
