21. marketplace prepare before you hit submit 21

22. 22 Do it right the first time It takes 5 business days to get published, so: Read App Cert Requirements guide  http://bit.ly/WP7-AppCert Build in Release Mode Test, Test, Test on RealDevice before uploading .XAP If publishing fails, you will get PDF file: Why it fails Steps to reproduce After you fix the failure, you will need to wait another 5 days :)

23. 23 Certification Status (1) Submission in Progress = You need to click the Submit button (or click it again!) to finish the submission. Ready for Testing = The app has been submitted, but hasn't been placed "in the queue" for testing. Testing in Progress = The app is in the queue and the next tester available will get to work testing it. The app will usually stay in this status until it is ready for signing or has failed certification.

24. 24 Certification Status (2) Ready for Signing = The app has passed certification and is awaiting the next signing batch so it can be published. Ready for Publishing = The app has been certified and signed, but you did not select the auto-publish option when you submitted it. You need to go into the app's detail page and publish it yourself! Published to Marketplace = The app has been through the entire process and is now "published".

25. 25 Certification Status (3) Certification Failed = The app has failed certification and you will need to change it before you submit it again. There should be a failure report that can be downloaded from the app’s detail page. (hint: The download is accessed from the Action dropdown.) None = It is unknown what this means. Apps with a status of None are sometimes delayed for several days. If your app has a status of “None” for more than 48 hours I would put in a support request.

26. 26 Marketplace Artwork Create icon from scratch Generic icon will fail your publishing status (5 days remember?) Screenshots have to be 480x800 Don’t forget the 1000x800 background image It’s used for “Featured App”, you want to make it pretty & right Don’t forget the 3 extra icons: 99x99 173x173 200x100

27. 27 Marketplace Screenshots Use the free Windows 7 Snippet Tool Zoom to 100% Disable Frame Rate Counter

28. 28 Marketplace Screenshots This app deploys .XAP But to Unlocked Device! Unlocked = users with Developer Account The same .XAP can be uploaded by receiver to Marketplace For sharing internally, not externally
