How do I share files (music, video, image) create by my app? I am interested in sharing audio file specifically.
Imagine I have a program that generates wav file. How do I take it from isolated storage?
Is it possible to sent an attachment with e-mail? Save it on SkyDrive? Share on Facebook? Put it to media library?
At least in some convenient for a user way to take it out from WP7 device?
Any help regarding this topic would be welcome
You cannot directly send it as an attachment through the EmailComposerTask, however you can use your own implementation of an email sending mechanism.
You can save it to SkyDrive, but then again you have to use a custom API layer (developed by you or by a third-party) to achieve this.
A better choice in my opinion would be having a WCF service that will transmit the byte array of the generated content to a specific location - this will ultimately give you more control over the transmission layer.
