Using VS 2003 and Cassini web server. I'm new to ASP.Net and so this may be a dumb
question.

I'm getting an error where the type 'FarmLand.WebForm1' is not found. The Codebehind
C# source file declares a namespace of FarmLand and a class of WebForm1.

Does one have to restrict which namespace one uses in Codebehind forms? Maybe match
the namespace the aspx file has?

When one adds a namespace then does one have to move the file to a subdirectory
(analogous to Java) and maybe that's why the class is not getting found?

Or is my error in some other direction?

Server Error in '/' Application.

Why you rename your codebehind file??
WebForm1.aspx
WebForm1.aspx.cs

may be this is the problem, I notice some problem when i rename my
codebehind Also.. but not "Not Found" error, there is a problem in your
webserver not in the page..
and you can name ure namespave whatever u want without thinking about folder
names at all..
