0) When I create a class, the App_Code folder isn't automagically created for me.

1) I've written a BasePage class that inherits from System.Web.UI.Page. When I type that out, intellisense doesn't change the color of Page like I'm used to (but it's not underlinedeither to indicate an error).

2) When I try to use the BasePage class elsewhere in the site, it says it can't find it when I try to view a page in the browser.

Is this all happening because I'm doing a web app versus a web site? If so, how can I fix it? I've tried moving the base page class to the root site folder, and that didn't help at all.

EDIT ==============

I also forgot to mention that when I created the base page classes, I had to add using System.Web.UI; to the tops of the files, but intellisense.

Also (and this is the big one) I created a new web site (as opposed to a web app), and all of the problems I described above disappeared. Why does it make a difference?

Hi John,
For a web application there is no predefined folder to keep the codes. Either you can directly add the classes, that is not the good way. So you can add a new folder (any name). As you are added the App_Code folder, the classes inside may have the namespace like Your application name.your folder name . So you have to access the classes like App_code.your class name. Else remove the folder name from the namespace, you can access the classes directly.

Hope this helps.

0) When I create a class, the App_Code folder isn't automagically created for me.
When you add just a class to the root for the first time, it should ask you to place it in App_Code folder. If it does not exists, it creates one. In case this has not happened with you then, try creating the folder manually and place the class file there. (Once you create the folder, it's color would automatically change to some other color then a general folder color.)

1) I've written a BasePage class that inherits from System.Web.UI.Page. When I type that out, intellisense doesn't change the color of Page like I'm used to (but it's not underlinedeither to indicate an error).

2) When I try to use the BasePage class elsewhere in the site, it says it can't find it when I try to view a page in the browser.
Looks like it did not configure correctly. It should change color and give access. Try with BasePage in App_Code if not done till now. I really doubt it should be because of WebApp & Website difference.

If after trying with App_Code folder, you are still facing the issue, do share across your observations, I would like to repeat & replicate it on my system.

Hi John - did you remember to update your web.config?

XML

<compilation debug="false">
    <codeSubDirectories>
        <add directoryName="VBCode" />
        <add directoryName="CSCode" />
    </codeSubDirectories>
</compilation>

Look here for more info[^]

It's just a thought :-D

Graciously, yours truly,

Hi John,

This what I did. I created a foder named Pages in the web application. Inside the Pages folder I added a Partial Class.

C#

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
namespace WebApp2.Pages
{
    public partial class BasePage:Page
    {
    }
}

WebApp2 is the application name.

Then at the Page markup I use it as follows

XML

<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"
      CodeFile="~/Pages/BasePage.cs" CodeFileBaseClass="WebApp2.Pages.BasePage" Inherits="WebApp2.Pages.BasePage"  %>

In an another test, I inherit this basePage class in the code behind like this.

C#

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using WebApp2.Pages;
namespace WebApp2
{
    public partial class _Default : BasePage
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            Response.Write("Hello");
        }
    }
}

In the markup

XML

<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"
      CodeFile="~/Default.aspx.cs"  Inherits="WebApp2._Default"  %>

However intellisense doesn't works, but it has no error and works fine. Is this example not work at your side?
