@RosarioPulella can you add the readme.txt here to the Controls package as well for #3782 (we should just include it as a loose file like we do the license of the other packages, just in the root).

Also, can you make sure we have an explicit WinUI 2.5 reference on all the sub-packages? I think we only have it on a couple, and we should probably ensure that we will be consistent against that style.

Thanks!

@michael-hawker Should be all good now

Thanks @RosarioPulella, once the build is finished, I'll validate it works as intended in VS! 🎉

Installing the world...

Woot, it worked! Everything looks great. 🙂

It just doesn't word-wrap, so I'll make a suggestion commit that and we're good.
