This
morning I decided to upgrade my cloud service project from Visual Studio 2012
to 2013. The upgrade requires installing the Windows Azure SDK 2.2, and then do
an automatic upgrade of the project.
On the
surface everything looked fine!
However,
when I started deploying the upgraded service to Azure, the deployment never
completed.
Having
spent quite some time trying different things with the Azure deployment, I
decided to try a local deployment in the emulator. I was expecting everything
to work fine, but I found out that my worker role just kept on recycling in the
emulator! It would call OnStart(), then Run() followed by a message that Run()
completed which triggers a role restart.
The next
logical step was to debug what was going on in the service, so I added
breakpoints to OnStart and Run, and to my surprise the debugger never kicked in…
By then I
concluded that something was completely broken. Next up, I tried creating a new
service from the Visual Studio templates, which worked and debugging also
worked.
After
comparing the project files, I finally figured out that Visual Studio 2013
upgrade had failed to upgrade the version of the Azure references!
I had to
update the csproj file and manually change the version number on the following references
|
Assembly
|
From
|
To
|
|
Microsoft.ServiceBus
|
2.1.0.0
|
2.2.0.0
|
|
Microsoft.WindowsAzure.Diagnostics
|
2.1.0.0
|
2.2.0.0
|
|
Microsoft.WindowsAzure.ServiceRuntime
|
2.1.0.0
|
2.2.0.0
|
|
Microsoft.WindowsAzure.Storage
|
2.0.0.0
|
2.1.0.0
|
After that
I also had to update the same version numbers in the App.config file of the
service and everything was working again.
