Is it OK with these? Please help!

I can't find out an example for which a page calls a master page.

I don’t have any problems at all in production. You should report the case through one request.

I've run the steps you provided to me. After having applied that, it says something like "you have successfully defaulted to Web development setting".

To have a new project for me by the Express version means to have a new web site. After I've created that, I found that the language within "Default.aspx" is still "VB".
