Need help resolving CS0246 Compilation Error

Hi Experts,

I have a .NET website that is approximately 25GB in size and becaus of this I do not have a full local copy for testing purposes.  I need to add a DLL that connects to a webservice.  And then reference the webservice and use it in a new page.  I need to do this by hand and not publish through .NET.

When I try it fails and I get a CS0246 Error message (missing reference).  Basically I'm trying to add a single page with code behind to a website by hand.  This is what I've done:

1. Checked Spelling - it's all good
2. Added a using statement (the using statement is where it is failing!)
3. Added a <@ Register Assembly statement to the page
4. Put the dll in the BIN folder
5. Checked that it is an application - I have other DLL's and they are working

Any other ideas.... is there somewhere else I have to tell the application that the DLL is usable?

You might want to try adding assembly reference in web.config compilation section like sample below:

<add assembly="System.Core, Version=, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>

Any chance that a different version of the DLL is being referenced already?

So i figured it out. The using statement that I added was the name of the DLL. The DLL exposed a different name and I didn't realize there was already a using statement in the file for that DLL. Intellisense picked everything up like it was supposed to in .NET so I thought everything was good. The solution was removing the using statement to the name of the DLL.  *embarrased*
