I tried updating the relevant Azure packages via nuget but still getting this exception.

If you have installed the latest CloudConfigurationManager from nuget you likely have 3.1.0 installed. I clicked the link to the plugin above, it says there is an update that uses 3.1.0 so upgrading the plugin will likely fix your issue. Alternatively, check to see if you have an out of date binding redirect in the config file, or add one to reference the version of CloudConfigurationManager you have installed.
