Parser Error Message when adding new C# Webform with codebehind inside .vbproj solution

Question

So I've inherited a .vbproj that was created using Visual Web Developer Express 2010. Inside the project file there are aspx.vb and aspx.cs files. The program works fine until I've added new C# class. Here are the steps that I did when I created the new C# webform and class:

1. I've created the new C# webform (CreateOrder.aspx) and the code behind file (CreateOrder.aspx.cs) in a separate project.

I did this because Visual Web Developer Express 2010 won't let me add C# webform and class (.cs) inside the existing .vbproj.

2. Then I copy and pasted the C# webform with the code behind file to the existing .vbproj solution.

3. When I run the program and open the webform.aspx, I'm getting the following error:

[Parser Error Message: Could not load type 'CreateOrder'.<br>
<%@ Page Title="Create Order" Language="C#" AutoEventWireup="true" MasterPageFile="~/Site.Master" CodeBehind="CreateOrder.aspx.cs" Inherits="CreateOrder"%>]

Solution Explorer

I understand that it couldn't find the CreateOrder class which is clearly inside the code behind class (CreateOrder.aspx.cs). I have it declared as public class CreateOrder : System.Web.UI.Page

The weird thing is there's a lot of existing C# webforms with code behind class inside the existing .vbproj. Not sure why my newly created class is throwing the Parser error message. Please help guys. Thanks!

Answer 1

Try importing your CreateOrder class. This will link the assembly for that class to the current project.
