[RESOLVED] BC30560: 'Default' is ambiguous in the namespace 'ASP'

[tongyin]

I had compiled the latest version of source code and my colleague tried to deploy to web server. But the server kept having the error as below. After rollback to previous version, it works fine.

The compiled codes work perfectly in testing server, which is also running Windows Server 2003. May I know the possible cause of this error?


Server Error in '/MyApp' Application.

[TheCPUWizard]

You have two different things called "Default". Either rename one of them, or fully qualify the reference.

[tongyin]

I checked the solution, only has default.aspx which already been excluded. I used aspnet_compiler.exe with command prompt to compile the project. Like aspnet_compiler.exe -p "C:\MyApp" -v / "c:\deploy" -fixednames. What do you mean "fully qualify the reference"?

[tongyin]

We have fixed the error in the new deployment. Actually the error caused by the old files not deleted during deployment. After delete all old files and deploy again, the error no more exists. Thanks.

Having a mix of old and new files that have the same code (and therefore duplicate names within scope - as I originally mentioned) will definately do it.

Glad you got it fixed. Please dont forget to mark threads as resolved, and to rate (using the little scales to the right of posts) people who tried to help.
