Preview: Azure Functions Open API (Swagger) support

Support for editing and hosting Open API 2.0 (Swagger) metadata in Azure Functions is now in preview. API authoring is a popular application of Functions, and Swagger metadata allows a whole network of Swagger-compliant software to easily integrate with those APIs. These features integrate with the existing Azure App Service API definition support. So you can consume your API on a variety of first-party services, including [PowerApps, Flow](https://blogs.msdn.microsoft.com/appserviceteam/2017/02/23/making-your-apis-available-to-powerapps-and-microsoft-flow/), and [Logic Apps](https://docs.microsoft.com/en-us/azure/logic-apps/logic-apps-create-api-app). You can also [generate SDKs for your API in Visual Studio](https://docs.microsoft.com/en-us/azure/app-service-api/app-service-api-dotnet-get-started#a-idcodegena-generate-client-code-for-the-data-tier). ​Read more in our team's [blog post](https://blogs.msdn.microsoft.com/appserviceteam/2017/03/30/announcing-functions-swagger-support/). * App Service * Azure functions * Features * [ App Service](https://azure.microsoft.com/en-gb/products/app-service/) * [ Azure functions](https://azure.microsoft.com/en-gb/products/functions/)
