Uno Support for Windows.ApplicationModel.Email
ShowComposeNewEmailAsync method is supported.
On Android, it lets the user choose the target e-mail application before composing the e-mail.
On iOS, it uses
MFMailComposeViewController but falls back to
mailto: in case user has not set up any e-mail account yet.
On other platforms, the
mailto: URI is used to try to compose the e-mail. This uses the
Launcher API to launch the URI, so works on all platforms where
Launcher is supported.
E-mail attachments are not supported yet.
