I created the simplest possible SharePoint Add-in using the default template in Visual Studio 2015. (SharePoint-hosted)
I deployed the Add-in to the SharePoint Online site of my Office 365 Developer Trial Account.
After that I change a single character in the "Default.aspx" file.
When I now hit F5, I get the following messages in the output window:
Skipping deployment step because a pre-deployment command is not specified.
Unexpected error when directly deploying file c:\users\matthias\documents\visual studio 2015\Projects\QuickTest\QuickTest\Pages\Default.aspx.
Access denied. You do not have permission to perform this action or access this resource.
Uninstall SharePoint Add-in:
This results in a complete uninstall / install cycle, which is way too slow for rapid development. ;) (1 - 2 minutes)
I heard that it is also possible to live update a file during a debug session by simply saving the file. This failed too.
Are there any permissions I need to setup to make this work?
