Hello VS 2005 World:

I am making my way through VS 2005 Beta 1 and I'm having a problem getting
ASP.NET project to start in IIS running on an XP development machine.

I build a sample project in VS 2005 and it runs fine through the debugger.
Then I try using the new Publish Web Site feature to publish the application
to IIS at C:\Inetpub\wwwroot\my_project.

It looks like everything gets published correctly to a virtual directory.
But when I go into IIS and configure the startup file to look for
Default.aspx then try and access the application in Exporer using this
address:   http://localhost/my_project/default.aspx.

I get this message:
----------------------------------------------------------------------------
---------------------------------------------------------
The XML page cannot be displayed
Cannot view XML input using style sheet. Please correct the error and then
click the Refresh button, or try again later.

'http://localhost/OneToMany2/default.aspx'. Line 1, Po...
This is a marker file generated by the precompilation tool, and should not
be deleted!

What the heck does that mean?

Can anyone give me a clue as to what I'm doing wrong here?

The virtual directory looks right, I see the code there and I don't see
anything unusual in IIS.  The application works fine through the debugger.
One note is that the machine I installed Yukon and VS 2005 already had .NET
Framework 1.1 installed.  Does this have anything to do with it?  I don't
think so because the new VS 2005 Web Configuration App runs fine...

Thanks

Confused and bewildered...
