hello I recently began to develop apps for SharePoint 2013 online on my Office 365 account. And I am getting more familiar with upgrade process. So I know how to upgrade app for SharePoint online. Only thing is to change version in manifest to higher version.
But my problem is that when I attach database to project(as
dacpac file) then upgrade fails and generates error
'The content database on the server is temporarily unavailable.
Details: 0x80070002 '
I always get this error. When I deploy app first time with database then everything is okay. But when want to upgrade database then I got this error. I can add that app is autohosted.
Any ideas what causes errors?
