Any ideas on how i can create this app?
1) i have a page which contains 3 tasks and thus has a textbox, a label to contain an image name and another label which is to display my current location..the first is to enter some text into a textbox, the second is to take a picture and come back to this page and display the picture url and the 3rd is to determine and display my location.
2) i need to gather each of these 3 bits of information and upload it to a remote database via WCF or Odata.
3) I know that for example, to either take a picture with my camera or browse to a pix in the pictures hub will take me away from my task page.
how can i take the picture and carry the information back to my task page without losing state?
When you take a picture, your application will be tombstoned. See the following article for details of how this process works and what you need to do:
