IDE :: Warning BC40010 In VS 2005 Project

Using VS 2005, I create a new VB .NET class library project. The project created is automatically populated with an "Any CPU" build target. I create a COM visible object, check the register for com interop and build the project. The resultant assembly is NOT registered in HKEY_CLASSES_ROOTCLSID. Instead it goes into HKEY_CLASSES_ROOTWow6432NodeCLSID. I have a 64 bit machine and 64 bit OS. I would swear that with VS 2003 on such a setup, I got an entry in the 64 bit registry hive.So I went to the configuration manager and specifically created a x64 config, copying from the (only) Any CPU config. But when I build I get two BC40010 warnings. One was for System.Data.dll. So I went to the project properties/References tab and then removed "System.Data.dll" (no mscorlib entry there - the other BC40010 warning) and then ran the add command and re-added System.Data.dll thinking that since I was working on the x64 config, the IDE would bring in the correct assembly.Still I get the warning. Why doesn't the IDE understand the meaning of the "x64" configuration the wizard created? The MSDN tells me I have to fix this:

To correct this error Examine the quoted error message and take appropriate action.Compile the program again to see if the error recurs.If the error recurs, reinstall the Visual Basic compiler.If the error persists after reinstallation, gather information about the circumstances and notify Microsoft Product Support Services.
