Add Dll reference in a webservice

[davidy]

Hi,

I have the following question:
I made a webservice in VisualStudio.NET that uses a Dll.
By clicking ad Reference i could select the Dll, this works fine.

But now i wan't to do the same in WebMatrix.
The problem now is that i can't find the option add Reference.

I tryed:
"Imports DllName"

Then i get the message:
Namespace or type 'DllName' for the Imports 'DllName' cannot be found.

Could somebody please tell how i can call a Dll in a WebService while using WebMatrix?

Thanx in advance
