IIS Applications vs. Virtual Directories
Paul Wilson writes: "I've even noticed that nearly everyone, including Scott Guthrie and Fritz Onion, incorrectly refers to Virtual Directories when what they really mean is IIS Applications. These terms are not interchangeable -- you can have a Virtual Directory without it being an IIS Application, and you can also have an IIS Application without it being a Virtual Directory. Being a Virtual Directory is not relevant to ASP.NET -- its just a logical way to organize your web-site and physical directories. "
Good point Paul, I think I've mixed them up myself when talking about this stuff.
