Azure Functions now supports a richer model for working with HTTP triggers in .NET isolated function projects.
Apps can now be written to use familiar types from ASP.NET Core such as HttpRequest, HttpResponse, and IActionResult. This makes it easier for function authors to leverage their existing skills from ASP.NET Core and existing in-process Functions projects.
The update also provides greater control over the request and response, enabling larger message sizes and streaming content types.
