Button: [UWP] ArgumentException is raised when targeting Windows 10 version 1809

When the Target version of the UWP project is Windows 1809, RadButton raises the following exception:

System.ArgumentException: Value does not fall within the expected range.

Outstanding. I'll add it to the style and see if it just works.

Hi Craig,

You can fix this by setting BorderThickness to zero:

<RadButton BorderThickness="0"/>

The reason the problem arises in 1903 (SDK 18362) is because Microsoft changed the behavior of UWP controls and default values for null when it's a non nullable property type. Traditionally, you'd use "-1", but that is no longer accepted and causes an OutOfRangeException Therefore, by overriding the default -1 value with 0, you avoid the exception.

Note: this also rears it's head in other places, like RadBorder. If you see this exception again, try setting BorderThickness to 0 on those controls as well.

Same here - Windows 1903 also experiencing the same issue.
