    Type not Defined. Going crazy!

    Hello,

    On an ASP.NET 3.5 web site App_Code folder I have a class named
    BoxesView under the namespace Engine.

    On an aspx page code behind I have the following:

    Protected WithEvents c As New Engine.BoxesVie w

    Then I added it to the page. BoxesView inherits composite control.

    I don't get any error when I write my code. However when I build the
    web site I sometimes get the following error:

    Compiler Error Message: BC30002: Type 'BoxesView' is not defined.

    Sometimes the page runs fine sometimes I get the error.

    I don't make any changes ... I have no idea why this is happening!

    I am on this for 2 hours.

    Why does my page either runs or display an error?

    And why I don't get any error in my code but only when sometimes when
    I run my page or build the web site?

    I am using VS 2008.

    Thanks,

    Miguel

      Miguel,
      It can be very tricky to work with the VS Web Site Projects. I always use
      the Web Application Project for exactly this reason since it all compiles
      into a single DLL instead of many dlls. Make sure that you are also
      importing the namespace correctly for your class that is coming from the
      App_Code folder.

      Hope this helps,
