One thing I’ve noticed is that when you create a SharePoint project in VS 2010 (File, New, Project) and create a name for your project it doesn’t get persisted down to the project item. For example, create a new Visual Web Part project; you’ll notice that your default naming convention follows VisualWebPart1 for the web part that is added to the default top-level SharePoint project.  If you create a new Visual Web Part project called MyFirstVisualWebPart you’ll see that the ensuing project item that’s created does not prompt you for a name for your web part
