I noticed the other day that when I took a photo on Windows Phone 7.5 I got the option to share it to lots of places, including Evernote and Flickr. As far as I know these are not standard sharing destinations and have probably been added as sharing options by their respective Apps after I downloaded them.
I have found the API to share a link to some of these services.
What I can't seem to find any info on is how I can share photos and other stuff to ALL of the services that seem to be available to the photo app.
I could do it by using the Evernote/Flickr/etc.. APIs myself, but this would require another OAuth signin for the user for each service, something that would not be required if I could leverage the system sharing options.
Can anyone point me in the right direction for how to do this?
Thanks, Andi
You cannot, as far as I know.
Apps can share to the targets you know - SMS, Email, Social/Link.
The built in photo app, specifically, is extendible in such a way that you can register your app to allow photos to be shared to it.
So, in other words, the only options you have (w/o coding them yourself) are:
Your App -> Email, SMS, Social
Photo -> Your app
