I am New at Windows 8 app development. I want to create an app which stores data in skydrive like this
<person>
<name>XYZ</name>
<geb>01.01.1992</geb>
…
</person>
How can I do this? I only find a version to send a value with an array index. How can I save data as XML or whole files like xml or pictures in the cloud?
You can use Azure mobile service to store data in cloud as tables. It is paid service and you can use it for commercial purpose. Here's some posts which might be helpful to you.
