With ASP.net MVC, one thing I always wondered is why we still had to have the code behind files. Looking at the FubuMVC samples, everything looks much cleaner without the additional files – with RC1, code-behind files are no longer required!

However, if your upgrading from beta, you will need to change your ASPX pages. In this post, I will cover the steps I went through to remove these files.

During beta, my solution looked looked like this:

In my code behind, I have a mixture of strongly typed ViewPage<T> objects and the standard ViewPage. As a result, in my ASPX page, I had a CodeBehind file and a Inherits tag.

With RC1, I can remove the CodeBehind tag and replace the Inherits to System.Web.MVC.ViewPage directly.

I can now delete Index.aspx.cs and Index.aspx.designer.cs leaving me with just the Index.aspx file.

If my ViewPage was strongly typed with a model, the the Inherits tag would include this, just like with the code behind model:

For ASP.net MVC User Controls, instead of ViewPage<T> you use ViewUserControl<T>:

Similarly with Master Pages:

After changing all my views, controls and master pages, my solution looks like this:

This makes me happy.

UPDATE: Parser Error Message: Could not load type 'System.Web.Mvc.ViewPage<ProductsMenuModel>'.

Ok – I made a little mistake. When I hit my ViewPage<T>, I received a Parser error message. If I had paid more attention to the release notes, I would have noticed I needed to copy an additional block of xml into my web.config.
