Delete the Web Apps DLLs and Everything Works

Here is another of my favorite problems with VS2005.

If I have a Web Application Project.  If I build it (with no errors) then when I try to view it I get the error below.  However,

Parser Error

Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.

Parser Error Message: The type ‘Company.Web.Equipment.Global’ is ambiguous: it could come from assembly ‘C:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Filesequipment3f386648c5a85b94App_Code.gv_z5p7w.DLL’ or from assembly ‘C:DataCompanyCompany.Web.EquipmentbinCompany.Web.Equipment.DLL’. Please specify the assembly explicitly in the type name.

Source Error:

Line 1:  <%@ Application Inherits="Company.Web.Equipment.Global" Language="VB" %>

Source File: /Equipment/global.asax    Line: 1

Version Information: Microsoft .NET Framework Version:2.0.50727.42; ASP.NET Version:2.0.50727.42


I don’t know why it is only happening with this one web app.

Very frustrating.

Update: This has been resolved.  The problem is obvious now.  This was a web application that had been converted to a Web Site Project.  When I tried to reimport the files manually into a new Web Application Project there was one minor, yet major, difference that was causing it to fail.  The “CodeBehind” attribute had been changed to “CodeFile”.  I didn’t think much of it at the time, but of course this indicates that it is going to actually USE the codefile when the page is accessed.  By having a CodeFile attribute AND compiling the code into a DLL, I was ending up with copies of every class.
