Console.WriteLine("Hello, World!");

If you have install “Windows SharePoint Services 3.0 Language Pack” and you see some fails like this

Go to C:\inetpub\wwwroot\wss\VirtualDirectories\[Port]\App_GlobalResources

And check if you have wss.[Language].resx file.

Example:
I installed WSS 3.0 En-Us at 88 port and I want to install Portuguese language pack.

Go to C:\inetpub\wwwroot\wss\VirtualDirectories\88\App_GlobalResources

Check if “wss.pt-pt.resx” exists.

If not, just copy it.

You can find this file in an WSS 3.0 Portuguese installation.
