I am developing a web application (C# VS 2008).  App works fine locally.  To publish to my host, I publish locally (using File System to a local directory).  Then, I manually FTP files to my web host.

When I try to run the page, I'm getting the following error:

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: CS0433: The type 'Core' exists in both 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\root\11dc5a36\51e0badc\App_Code.okyxvrfm.dll' and 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\root\11dc5a36\51e0badc\assembly\dl3\02b50bd1\76c9bdf0_a182cb01\App_Code.DLL'

Source Error:

Line 20:        
Line 21:
Line 22:         SqlConnection connection = new SqlConnection(Core.CONNECTION_STRING);
Line 23:         SqlCommand cmd = new SqlCommand();
Line 24:         SqlDataReader myReader = null;

The Core.CONNECTION_STRING holds my db connection string.

This only occurs when I run the app on my web host.  Any ideas?
