The default install of Visual Studio 2005 does not include 'web application' support. When opening those projects, you receive an error: "The project type is not supported by this installation."
Googling for solutions brings you various pointers to install packages like SP1 and the MS "Update to Support Web Application Projects." But I find I am never able to get the install down to a sequence of steps that always works, I'm always fuztzing around with re-installs and in the end don't know how I exactly came to a working install.
Does anyone have good instructions or pointers for how to do this?
