In a previous blog, I showed you how to include configurable settings in your Windows Azure cloud applications. Unlike your web.config or app.config files which have to be redeployed to the cloud before they can be used, role settings can be updated at runtime and take affect immediately. No redeployment of your cloud solution is necessary.
To achieve this, simply login to the Windows Azure portal and access your cloud service. Click on the Configure tab and scroll down to where your settings are defined. Modify any of your custom settings and click on the save button. Windows Azure may take some time to apply the new settings, but no re-publish or deployment to the cloud is required!
