If you are developing a web site using the Web Application Project model, then you know that the Project File is an integral part of this model. In order for a file to be considered part of the Web Application Project, it must be included within the project file. This is also true of Assembly References and other project metadata settings. If a file exists in the web’s file-system root, but is not included in the project file, it is not considered part of the project and will not be included in the MSBuild based compilation process.
Since the Project File is so important, there may be an occasion during which you would want to view this file and even edit it manually (although this could be dangerous and is done at the user’s own risk). Did you know that you don’t have to leave Visual Studio to do this?
Here is how:
