Improved support for Azure AD B2C in App Service

In a recent service update, we improved our overall support for Azure Active Directory (Azure AD) B2C in Azure App Service. This includes enhancing our existing web app support, but more importantly includes adding full support for leveraging Azure AD B2C in mobile, API, and function apps. More specifically, support has been added for the [Easy Auth Token Refresh API](https://cgillum.tech/2016/03/07/app-service-token-store/). Additionally, the Login API has been updated to support specifying specific Azure AD B2C policies as arguments. If you’re a mobile app developer, these improvements will make using Azure AD B2C in your mobile app _significantly_ easier. For more details about these improvements, a few code snippets, and a demonstration of these Azure AD B2C capabilities in a simple demo web app, go to the [blog post](https://blogs.msdn.microsoft.com/appserviceteam/2016/08/15/app-service-auth-and-azure-ad-b2c-part-2/). * App Service * Azure Active Directory B2C * Features * [ Azure Active Directory B2C](https://azure.microsoft.com/en-gb/services/active-directory/external-identities/b2c/) * [ App Service](https://azure.microsoft.com/en-gb/products/app-service/)
