Code Behind vs Code Seperation

The pre-whidbey code-behind model used inheritance which had plusses and minuses from a development perspective.  The new model uses partial classes for web environments.  After some experimenting with Whidbey I'm becoming somewhat anxious as to the new programming model.  

It seems that I will be unable to seperate logic completely from user interface, as with the current model, I can build the assembly for the application and deploy it, and leave the aspx files seperate from the assembly. This allows us to change the user interface after deployment, or provide quick hotfixes by overriding methods using server-side script tags. I have heard that the options will be to release the source code with the site, which I find to be unacceptable from an IP standpoint, or to compile everything into a single assembly.
I prefer the environment that I have set up for development and deployment, as it allows me to schedule builds of a web application much like I would a windows application, and manage a structured escrow and release process, the model I'm seeing for Whidbey seems to go against that method of thinking.
I've noticed that a "Web Site" is a seperate project type than a standard project, and I seem to be unable to create a complex web project with both ASPX and custom classes and components.
Finally, Although I still have some reading and experimenting on the possible values of the @Page directive in whidbey, it seems to me it is not possible to inherit the page from a different class. Before I could add new functionaity to a base class that inherits from System.Web.UI.Page and change the page inheritance to my base class. Is this still possible?

With Whidbey you can separate logic from interfaces. Just simply call your other layers components from the partial code. You can use separate assemblies with no problems, add them to the \bin folder. You don’t need to use the new \code folder if you don’t want to distribute your source codes. You can now even protect your .aspx pages.

This is done with the pre-compilation tool. This tool will compile all of your code including web forms and user controls etc into assemblies, so no one can see how the UI is implemented.
You can schedule the aspnet_compiler.exe to recomile your web project, or you can compile your whole solution.

I can’t see why you shouldn’t. You can create a solution and add web site project and class libraries just like before. But with the alpha version you can’t add references to the web project, the reference feature is rebuild from the beginning and will be available in the beta timeframe.

Yes, it’s still possible:
<%@ page language="C#" inherits="Test.MainPage"%>
using System.Web.UI;
namespace Test
public class MainPage: System.Web.UI.Page

Code behind vrs. non code behind in VS.NET 2003
Does anyone know what the advantages and disadvantages are for using code behind vrs. non code behind in Visual Studio.Net 2003? One important difference is that you are able to separate the design of a web site from the code. This makes for ease of maintainablity and much more structured applications. If you ever worked with classic ASP the code-behind is a great invention. sivilianMy Weblogs...

what about the code-behind (code behind)
One MAJOR difference between AJAX.NET and Atlas.NET seems to be that AJAX.NET is able to expose methods in your codebehind to the client. Why doesn't Atlas do this? Or am I mistaken? With AJAX.NET it's just a simple line or two:  Ajax.Utility.RegisterTypeForAjax(GetType(myClass)) <Ajax.AjaxMethod()>Public Function myFunction PLEASE tell me Atlas has something comparable to this. I don't have the time to rewrite all my code-behind methods in javascript or atlas script. All you need to do in Atlas to expose a method on your page (or its code behind class) is to put a [WebMet...

Code Behind or not Code Behind
Ok i am confuse now.... A lot of books are showing pages without code behind (the code is integrated in the .aspx) Is it better to use the code behind or not. Is there any difference between using VB.NET or C#.NET except for the code synthax. Thank you and come again. A lot of samples show inline code just for simplicity.. i personally use code-behind because I like to seperate my code from presentation. As for VB.NET or C#, its your preference.. there is no difference really when its all said and done. From a purely mathematical sense, having everything in a single file would s...

Code Inline Vs Code Behind
 I recently started learning and coming from a php background a tend to favor code inline as oppose to code code behind. But most professional articles are using code behind which indicates that it is the insdutry standard. I am really not sure which one would be more beneficial to me here. Please let me know your guys's opinion on this. Should i learn code inline first and then code behind or go straight to code behind?  I have to say so far code inline appears easier to understand, but code behind makes sense (separating logic from the User interface). Also, would you...

I hear these terms thrown around alot but cannot find a definition. I am using webmatrix.(is it a step down from Dominatrix?)

Code Blocks vs. Code Behind
I'm currently building an ASP.Net MVC demo for our company, with the goal to win them over that it is a feasible pattern/framework for us to use.  One thing I'm struggling with is the benefits and drawbacks to to using code blocks, <% %>, to fill the page with data, create forms, etc., versus using server controls and filling their values in the code behind. I know this is a loaded question, but any argument for or against would be welcomed. Hey! I would like someone to answer this as well!  To me adding inline scripting blocks (<%%>) reminds me of classic a...
