I am using VS 2008 and C# but when I added namespace in web.config file, that namespace is not imported or included in code behind or aspx I
web.config
code behind or aspx
The purpose of the namespace section is to get around having to do the import in the .aspx page. Code behind in C# still requires you to have the using statements at the top of your .cs file.
There is no way to get around this.
