404 Page Not Found when running page from VS2010

I have a couple of pages that I'm testing out running from Visual Studio. One is a page that creates a content block from code and the other does a search query on content.

My problem is that the content block page works just fine, but when I try to run the search page from VS2010 using "View In Browser" it tells me:

Server Errror In '/' Application.
Page not found

I'm using Sitefinity 4.4 locally on my laptop.

Thanks for any help,
Jason
