CS1591 rule has been disabled for this project, which means we are not validating if all public types and members have xmldoc in them.
Unfortunately at the moment we can't enable this rule as it will break the build given that some compiler generated types don't have proper xmldoc (thanks a lot Microsoft... not!)
I've enabled the rule temporarily and noticed that these are the types with missing documentation, so I'm now adding them back.
Adds missing documentation to public items
@PedroLamas, Thanks for signing the contribution license agreement so quickly! Actual humans will now validate the agreement and then evaluate the PR.
