Class in App_Code not accessible

Question

I have a Config.cs file inside the App_Code folder:

namespace C
{
public class Config
{
  ......
 }
 }

In my default.aspx.cs page, I added using C; but I can't load the page. It says:

CS0246: The type or namespace name 'C' could not be found (are you missing a using directive or an assembly reference?)

I'm using CodeFile instead of CodeBehind and I already tried to set the Build Action property to Compile but I cant find that option in the class properties page. I am using VS 2012.

It works fine though when I press F5 in VS 2012 and access my site under that port. It only show error when I try to access my page directly, as any other user would try to.

I think your App_Code folder is not in root folder of project. Please make sure that you have put App_code folder in project path which contains default.aspx file. Don't keep App_code within a nested folder.

App_Code folder is already in my root folder. In my `inetpub` folder there's a folder named `painel` and inside that folder there's all my aspx pages, including `App_Code` folder. – Leandro Battochio Jan 12 '13 at 17:26
just open your website in VS from path .../inetpub/painel1/ and then try to compile.. – sreejithsdev Jan 12 '13 at 17:30
I solved it by moving the `App_Code` from `painel` directory and placing it under `wwwroot` folder along with my `web.config` file. Odd, but it works fine now. Thank you. – Leandro Battochio Jan 12 '13 at 17:34

Try to pre-compile the application and publish on server. If it is not precompiled, make sure the class file exists in server 'App_Code' folder. When the application receives first request, this class gets compiled.

You should just edit the Properties of the class files in Visual Studio and mark the Build Action as "Compile", instead of "Content", then rebuild and re-publish your project.
