Visual Studio 2005 Web Application Projects
Microsoft has updated the addin: VS2005 Web Application Projects. This will allow you to create web applications that behave more like they did in VS2003 (so you don't have to use the VS2005 'Website' project).
Features include: * compilation to single assembly in the \bin folder * project file that contains all files related to the project (allows you to hide files) * allows direct migration from vs2003 web applications
Update: Here's an alternate download. I'm not sure what the difference is though.
