Why asp.net can't find my namespace if I already added the reference dll to the project?

I have a simple ASP.NET 3.5 project in c# to test out the code from
http://www.codeproject.com/KB/database/mysqlmembershipprovider.aspx
This code just uses a couple of files that require a reference to MySQL.

I already installed the MySQL data connector for .Net and already added the reference to that dll to my project.

I already created an "App_Code" folder to my project and placed both files in it.
Also tried changing the property "Build Action" of each file to "Compile".

Anyway, no matter what I do, I get the error below as if I did not have a reference to "MySQL.Data" which I definitely have.

Compiler Error Message: CS0246: The type or namespace name 'MySql' could not be found (are you missing a using directive or an assembly reference?)
Source Error:
Line 4:  using System;
Line 5:  using System.Data;
Line 6:  using MySql.Data.MySqlClient;

They mentioned in the description that the classes DOESN'T work with MySql.  They work with ODBC so you might want to use an Access database.
Hope this helps.

I hope that you have checked in "Reference" list  that MySql.Data entry is displayed.

This happened few times for me and it worked fine once I restarted visual studio.
Also try to copy the dll to bin folder of the application and try again

Thanks, I did have the "MySQL.Data" dll visible under my "References" listbox but anyway, I followed your advice and copied the file from GAC to my "Bin" folder and that took care of it.  Why ? I don't know.  Good thing is that it works!
Thank you.
