Error in ASP.net : BC30037: Character is not valid

I have started learning asp.net. I went through basics and now i am started to build small application. I am using VS 2012 and created Empty Web Application Project with VB.

I can see web.config created automatically and following are the line written in it :

<?xml version="1.0"?>

<!--
  For more information on how to configure your ASP.NET application, please visit
  http://go.microsoft.com/fwlink/?LinkId=169433
  -->

<configuration>
    <system.web>
      <compilation debug="true" strict="false" explicit="true" targetFramework="4.5" />
      <httpRuntime targetFramework="4.5"  />
    </system.web>

</configuration>

I created Default.aspx file and wrote following lines of code :

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Default.aspx.vb" %>

<%
    HelloWorldLabel.Text = "Hello, world!";
%>


<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:Label runat="server" id="HelloWorldLabel"></asp:Label>
    </div>
    </form>
</body>
</html>

When I am running this application on browsers, I am getting following error that page :

Compilation Error

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately. 

Compiler Error Message: BC30037: Character is not valid.

Source Error:


Line 2:  
Line 3:  <%
Line 4:      HelloWorldLabel.Text = "Hello, world!";
Line 5:  %>
Line 6:  

Source File: c:\users\anjum.banaras\documents\visual studio 2012\Projects\Students\Students\Default.aspx    Line: 4

Can any one help me on this ? I am just beginner on asp.net. Your help can save lots of my time.

Thanking you in advance !!

I copied my code to another editor (notepad++) and was able to see the problematic chars. After i removed them, the code worked again.

��myClass.myArray(28) = "myFirstValue"
��myClass.myArray(29) = "myValue"

I was getting this error since my designer file was missing from the solution (I don't know how,seriously). So try adding a designer file for the aspx file in the solution; it worked for me.

You've set the programming language of the page to VB (Visual Basic), but the line it is complaining about is written in C# syntax. Either change the line to be valid VB code:

HelloWorldLabel.Text = "Hello, world!"

(I think that removing the ; is all that's needed, but I never code VB so I'm not sure)

or change the page language to C#:

<%@ Page Language="c#" AutoEventWireup="false" CodeBehind="Default.aspx.vb" %>
