ASP.NET Without Project File
asp.net
Solution
Are you sure it's not a Web Site Project, as opposed to a Web Application Project? Web Site projects do not have project files - you open a folder rather than a project file. See here for the differences between the two.
To check, each page of a Web Application project will have a .aspx, a .aspx.cs and a .aspx.designer.cs, whereas the Web Site project pages don't have the designer files.
Problem
I've got a ASP.NET project without the .proj file. How do I recreate the project file, so I can work on it on my machine? Is this possbile?
