Exception after upgrade to June 2012 SDK

Question

I had a project up and running with the November 2011 SDK and recently upgraded to the June 2012 SDK. When I first saw the error, I attempted the obvious - remove references and add the later versions, but that didn't help. Somehow it seems that version 1.0.0.0 is still being requested. I've also attempted to remove the reference and add the old version back, but no luck.

Here's how it shows up in my code. The first Trace.WriteLine that hits now reports the following exception:

System.IO.FileLoadException was unhandled by user code Message=Could not load file or assembly 'Microsoft.WindowsAzure.Diagnostics, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.

How can this be solved?

Answer 1

Check the web.config / app.config for all your roles. Make sure that you change the version number for any reference to the Microsoft.WindowsAzure.Diagnostics assembly to version 1.7.0.0

Answer 2

All your azure assembly references in your web/worker role projects should point to 1.7.0.0 Versions. Your ccproj files should contain

<ProductVersion>1.7</ProductVersion>

to ensure that the Azure instances contain the proper base assemblies.

You could also check if Microsoft.WindowsAzure.Diagnostics is copied to the output/azure package.
