title: Error renaming ASP.NET MVC project
body: <p>I have copied a previous project and renamed it. Once I had successfully renamed all the name spaces and it build correctly. I got the following error when I ran the application:</p>
  
  <pre><code>The following errors occurred while attempting to load the app.
  - The OwinStartup attribute discovered in assembly 'User Manager Interface' referencing    startup type 'User_Manager_Interface.Startup' conflicts with the attribute in assembly   'Service Monitor Web Interface' referencing startup type  'Service_Monitor_Web_Interface.Startup' because they have the same FriendlyName ''. Remove or   rename one of the attributes, or reference the desired type directly.
  To disable OWIN startup discovery, add the appSetting owin:AutomaticAppStartup with a value of "false" in your web.config.
  To specify the OWIN startup Assembly, Class, or Method, add the appSetting owin:AppStartup with the fully qualified startup class or configuration method name in your web.config.
  </code></pre>
  
  <p>I have figured out that if I comment out the first line below then the error goes away.</p>
  
  <pre><code>//[assembly: OwinStartupAttribute(typeof(Service_Monitor_Web_Interface.Startup))]
  namespace Service_Monitor_Web_Interface
  {
  public partial class Startup
  {
      public void Configuration(IAppBuilder app)
      {
          ConfigureAuth(app);
      }
  }
  }
  </code></pre>
  
  <p>I renamed my solution from User_Manager_Interface to Service_Monitor_Web_Interface.</p>
  
  <p>I cant seem to find any places with the old name, howevel in the error it mentions it.</p>
