It has been a while since I've published my app to Azure. During that time frame, I've upgraded my system from 32-bit to 64-bit meaning a fresh install of Windows and Visual Studio. And Visual Studio Update 3 came out and was applied. When I went to publish an update today, I received the following:
The following exception was thrown trying to publish: Root element is missing.
My web.config file looks fine so I don't think it's this issue.
The app works fine in debug mode so I don't think it's any of the .lsml files as is mentioned here.
And I tried this procedure to hand edit the .ls3proj file but it didn't seem to help.
I previously had an issue trying to publish when I upgraded from the standalone LightSwitch 2011 to Visual Studio 2012. I was able to overcome that issue using the method described in this thread.
Attempting to use this same method resulted in my new project has a full screen error saying "There are critical errors in the application definition metadata..." and 210 individual errors (max errors reached).
The first error, "Cannot create unknown type '{http://schemas.microsoft.com/LightSwitch/2010/xaml/model}GlobalAttributeGroup'." Doesn't make sense because that line in the .lsml is identical from the old project to the new project.
The second error, "Could not find any application definition in the project." Which I do not understand at all.
I am able to publish a simple "Hello, world" style app to my Azure account.
What could be causing this? How can I get more information about exactly which element is causing the issue? The log produced by running devenv /log was not helpful.
