“SetConfigurationSettingPublisher needs to be called before FromConfigurationSetting can be used” Error on Azure SDK 1.3

Last week I was trying to demonstrate accessing Azure Table Storage after I upgraded to the Azure SDK 1.3. During the demo I kept getting the exception “SetConfigurationSettingPublisher needs to be called before FromConfigurationSetting can be used” even though I had written this code and my demos all worked fine previously. After some digging and some help from a delegate who had seen this problem before I removed the sites configuration from my ServiceDefinition.csdef file.

   <Site name="Web">
       <Binding name="HttpIn" endpointName="HttpIn" />

My demo’s suddenly started working. The sites configuration is part of a feature to allow you to host multiple websites within a single web role. (This also explained why all my projects wanted to be upgraded when they were opened). Steve Marx has written a blog post which details the fixes and reasons why this issue arises. I have now moved my code for SetConfigurationSettingPublisher from my web role OnStart to my Global.asax.cs Application_Start. My demo’s now work correctly :)
