This article mainly focus on Azure Functions v3, dotnet-5 isolated. As per document, it is suggested that dotnet-isolated is way forward. Like every new feature this also comes with some advantage and some drawback or some functionality not supported as of now. (dotnet-6 is will be more integrated.)

If anyone worked on asp.net core then Middleware is not new but it is new to Azure Functions and specially with dotnet-isolated.

Overall, from my point of view this is good thing in dotnet-isolated and we can hook the middleware. In upcoming articles will try to use middleware for authentication and authorization process. It will look something like this.
