the default build type is not very satisfiable, and the not so old VS 2005 Web Application Projects also is not good

once I create a WAP, and I put a folder App_code in it, I build it ,  I got a dll, then, when I fresh browser, the builded dll and the class in App_code folder   will build together by  aspnet_wp, then I got an error.

so I try modify the aspx file, CodeBehind -> CodeFile, it worked well

since I want to deploy it , I just only build it once

but I think it may be get some another instable I don't know 

I don't like build it every time, and also, I don't like open a slowly web site

yes, because I try convert Visual Studio 2005 Web Site to the new  Visual Studio 2005 Web Application Projects

my project name is Panda.Web.Test, the output dll name also is Panda.Web.Test.dll

I put a folder App_code in visual studio manually, and visual studio can recognize it as a special folder

in app_code I put a class webutility.cs

the error occured when I browser a aspx wrote like

<%@ Page Language="C#" AutoEventWireUp="true" CodeBehind="test1.aspx.cs" inheite="test1" %>
<script runat="server">
  void Page_Load()
  {
        webutility.getAllControls();
   }
  </script>
....

......

it said class webutility can be find in apsx_23746f.dll and  34578.Panda.Web.Test.dll  in Temporary ASP.NET Files
