Can we see some Unit Tests with this PR? @AdamYoblick and @zsd4yr have some examples elswhere in WinForms.

@merriemcgaw I would love to have some unit tests for this, but it was unclear how that can be accomplished. I was waiting for an example or the scaffolding of a unit test project to be available.

Also, I thought the tests @AdamYoblick were pretty basic and not UI tests. The Dialog blocks the calling thread and needs UI automation to manipulate it. I fully agree on the need for tests, just had not seen any infrastructure for adding one in yet.

I can certainly add something to https://github.com/dotnet/winforms/tree/master/src/System.Windows.Forms/tests/functests if the p2p ref works now; I know that was being looked into before.

@onovotny Could you possibly provide before and after screenshots of the Folder dialog.

@merriemcgaw Done

This was an epic PR

Awesome to see this sort of transparency w/ Windows Forms!

Been waiting for this since Windows Vista 👍

Was the icon updated? The screenshot shows that it has the default form icon.
