What is the difference between CodeFile="file.ascx.cs" and CodeBehind="file.ascx.cs" in the declaration of a ASP.NET user control?
Is one newer or recommended? Or do they have specific usage?

A:
CodeFile is newer, it's introduced with ASP.NET 2.0, while CodeBehind is there from the start.
A longer explanation on what each of the names does can be found at this good blog post:

It all comes down on what gets compiled, when and where.

A:
CodeBehind = Needs to be compiled ( asp.net 1.1 model) and compiled binary is placed in the bin folder of the website. You need to do a compile in visual studio before you deploy. Good model when you do not want the source code to be viewable as plain text ... for example when delivering to a customer who you not have obligation to provide code.
CodeFile = You provide the source file with the solution for deployment. ASP.NET 2.0 runtime compiles the code when needed. The compiled files are at Microsfot.NET[.NET version]\Temporary ASP.NET Files.

So, does this mean that the developer must manually change the attribute of the Page directive or is there a way to create a web project which selects codebehind or codefile, by default, each time a new web page is added?

The way i see it is CodeFile is meant to be used for a "WebSite" and "Codebehind" is meant for a "Web Application Project" as it needs to be compiled. So while converting a "Website" to a "Web Application Project" we may need to manually change all CodeFile occurences to Codebehind!
