ExceptionCondition
ArgumentException

Either firstPackUri or secondPackUri is not an absolute URI.

-or-

Either firstPackUri or secondPackUri do not begin with a "pack://" scheme.

If both firstPackUri and secondPackUri are null, ComparePackUri returns 0. When comparing pack URIs, a null URI is always less than a non-null URI. For cases where firstPackUri and secondPackUri are both absolute pack URIs, ComparePackUri performs the comparison.
