I have created an "App for SharePoint" project in Visual Studio 2013 and selected the "SharePoint-hosted" hosting option. I am getting error "HTTP 404 The resource cannot be found" when I debug the project (i.e., press F5) in Visual Studio 2013 or if I "deploy" the project in Visual Studio, then browse to the site and click on the app in the browser. The URL of the app is http://app-a84df74e236d90.app.com/sites/development/SharePointApp1/Pages/Default.aspx.
I carefully followed this article to configure on my single-server virtual environment for app development/deployment and create my isolated app domain (app.com): http://msdn.microsoft.com/en-us/library/office/fp179923(v=office.15).aspx. I also made sure I didn't use a host header when I created my web application in Central Admin (I have seen that come up in discussions about this same error before). The article I referenced above mentions that Visual Studio edits my hosts file automatically, but I don't see any evidence that my hosts file has been modified. Is there some other configuration I need to do to allow this? Thanks in advance.
