firebird & cassinni & asp.net

Found the answer
<%@ Page Language="C#" CompilerOptions='/R:"C:\Program Files\FirebirdNETProvider1.7\FirebirdSql.Data.Firebird.dll"'%>
Excuse the newbie question.
I trying to use the .net provider to connect to a data base on a development machine using cassinni as the web server
in my aspx file the first two lines are
<%@ Page Language="C#" %>
<%@ import Namespace="FirebirdSql.Data.Firebird" %>
then the rest of the code.

The problem is when I view the webpage I get an error that the namespace could not be found. If I check the GAC the namespace is listed.

Any ideas?

Thanks,

Fr. Robert
