Version 1.12 of my PhotoAlbum
web application was built using the "New website" menu in Visual Studio 2005. This creates a website project, which I was curious to try, as I didn't have any experience with it. I come from ASP.NET 1.1, where the model is very different. For example, you precompile the website before deploying it (in ASP.NET 2.0, it's not compulsory; you can deploy the ASPX files together with the CS files and it is compiled on demand). Also, in ASP.NET 1.1, you have total control on the DLL, for example you can set the name, assembly information (version, company name, etc...). In the 2.0 website model, the project properties are very limited. Even if you precompile the website before deploying it, you don't have that kind of control over the DLL. Thankfully, Scott Guthrie
and his team at Microsoft released already a few months ago a Web Application Project
(WAP) template for Visual Studio. This template allows the same kind of control over the web project as in 1.1, but with all the added features of 2.0. For a web application developer, it's a life saver.
The WAP makes the web application much closer to an application than to a website. The 2.0 website model is quite OK for a website, where the content is more important than the functionality, but is not sufficient (IMHO) for an application, where versioning, for example, is crucial. The same application may be deployed on different sites, with different versions, and it's really important to be able to differentiate the versions easily. Also, the application is a product, so naming and setting properties is very important, as a part of the product identity.
WAP with included and excluded files and folders
For the PhotoAlbum, I had to come to the conclusion that the 2.0 website model is not adapted, and I decided to convert it to a Web Application Project. It's actually very easy, but one point must be observed: In 1.1 web apps, I used to place code-behind files manually in an "App" folder. This made deployment easier, because you could make rules like "All files under the root must be copied to the web server, and all folders starting with a non-capitalized letter". For instance, the folders "script" and "layout" would be copied, but the "App" folder wouldn't. Of course, this was not automatic, and you had to manually set the "Inherits" attribute of the "Page" directive to the correct path.
Page directive pointing to non-default classes and locations
In WAP 2.0, however, it's not possible anymore. In ASP.NET 2.0, the compiler automatically generates a "designer.cs" file, using the partial class feature which was not existing in 1.1. In this generated partial class, the web controls are declared, so that the developer doesn't have to manually add them to the code-behind (that was a tedious task in 1.1). Unfortunately, the compiler is not able to do that if the code-behind file is not where it is expected, and this is in the web application root (together wth the ASPX file).
Well, it's not that bad, because you can now automatically publish the web application (using Build/Publish in Visual Studio 2005), and only the files needed on the server are actually copied. But still, and even though the "designer.cs" makes the developer's life easier, it bothers me a little that I cannot organize my source code files like I want.
Anyway, I guess I must stop being a maniac for now, and just leave the code-behind files in the root.
