Thank you for your response.
I had already seen that article before I posted my question. Perhaps I am not stating what I want well enough.
I have an ASP.NET 4 code (C#) app and I would like to know if I can integrate that code in a single Azure Role with server-side node.js code.
In other words, is it possible to have some node.js connections running in the same Web Role as my C# code?
Parts of my app use web services that are contained in the same Web Role as my app. I would like to know if I could do something similar with node.js.
So, can I use server-side node.js in a single web role that contains the rest of my app or not?
Thank you.
