Changes to use the library in .Net 7 winforms app

[statler]

Made some changes to get your (really useful) auth working for me in a .Net 7 winforms app.

Changes:

• made some classes more accessible to hook in from a winform - didn't have access to necessary methods.
• A few library updates, but they weren't essential.
• adds the true to the project file in WPF. This shouldn't affect WPF at all
• change parameter type to WebAuthenticationBroker AuthenticateAsync to support management by a winform as well as WPF

It would be great if you could incorporate this into your published library. Happy to discuss.

Frankly I would prefer if it were native winforms app, with it's own native UI. How is this interoperability with WPF controls done?
