I have created an app that makes use of file types that are not standard to Windows Phone and I have registered my app to these extensions and they can be opened in my app perfectly from example the email client.
My application can modify the file as well as generate completely different ones. I then have an internal file manager page where users can delete files and choose to open then.
My problem now is that I want the user to share these files via email, Bluetooth, tap+send(nfc), etc. with a menu pretty much like the you get in the gallery(photos) app on Windows Phone. Is this a standard function that I can somehow access, or is there another standard library or anything really that I can use to as quickly as possible implement file sharing?
