Could not load file or assembly 'System.EnterpriseServices

Question

Hello Guys,
I"m new to Oracle and .Net, I'm trying to display data in a gridview but when I run my Asp.net application I get this error: "*System.IO.FileNotFoundException: Could not load file or assembly 'System.EnterpriseServices, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified*"
I am not sure wat this means and I have been searching the internet with no success. I'm using Oracle 9i Client 9.2.0.1.0 and I downloaded ODP.NET Version=9.2.0.700 just recently. Cud this have caused the problem????
Here is a snippet of my code and the program bombs at conn.open(), it seems like it cannot read my connectionString.
public DataTable FetchData(string statement)
DataTable dt = new DataTable();
string constr = "Data Source=PSM1;User ID=CHRHRDM;Password=CHRHRDM";
//conn.ConnectionString = "Data Source=PSM1;User ID=CHRHRDM;Password=CHRHRDM";
OracleConnection conn = new OracleConnection(constr);
conn.Open();
OracleCommand cmd = new OracleCommand(statement, conn);
cmd.ExecuteNonQuery();
OracleDataAdapter adapter = new OracleDataAdapter(cmd);
adapter.Fill(dt);
//cmd.Connection.Close();
conn.Close();
return dt;
And this is wat I see in my Event Viewer:

Hi,
For anyone with a similar error, I added System.EnterpriseService reference to my project. Now I can see my data on the gridview.
Thanks
