Does C# code contained in Javascript still need to be compiled?

Question

We have a web application built with C# and ASP.NET. I have to reference a few .NET session variables in my JavaScript code, so I use the following line to do so:

var layoutID = '<%=Server.UrlEncode(string.Format("{0}", Session["layout_id"]))%>';

This works just fine. The web application is built and published to our web server. If I want to make a change, a .NET change would require me to compile the changes and publish it to the web server again. If it's a JavaScript change, I can simply edit the js in the .ASPX page and the fix is immediately picked up...no compiling needed.

My question - what if I make a change to this inline C# code contained in JavaScript? Say, for example, I meant to access Session["layoutid"] without the underscore. Could I just edit the .ASPX page on the web server, or will this require compiling just as if it were in a .CS file? I'm guessing since it's C#, I will still need to compile for the change to be picked up. And yes I could just try it and see for myself, but I was hoping someone could give a little insight into what goes on behind the scenes with this inline c# code. And while we're on the topic, is the technique I'm using to access .NET sessions variables in JavaScript the most efficient way to do it? Bonus question - what is this technique called? I tried searching for an answer but I wasn't sure what to search for other than "in-line c# code JavaScript".

Thanks!

No, changes to ASPX/CSHTML files don't require re-compilation.

Note: whether it is good idea to jump on production server and change random code bypassing source control/testing is question to discuss and answer by your team.
