Getting a simple function to run in the CLR . Please help :-(

Hi everyone,
If anyone can help me with the following, I would be very greatful.
I want to create a pretty basic function under sql server 2005's runtime.
I've made the assembly and attached it. And when I do something totally simple
like return a simple string it works fine. However when I try and use a connection
object I get an exception as follows:
A .NET Framework error occurred during execution of user defined routine
or aggregate 'GetRolesString':
System.Security.HostProtectionException: Attempted to perform an operation
that was forbidden by the CLR host.
The protected resources (only available with full trust) were: All
The demanded resources were: UI
It seems to be suggesting that everything is protected and so I can't do
anything. That would be fine but I havent a clue how to unprotect them.
The things I've tried are:
1. Making the database property Trustworthy equal to true
2. Marking the Permission_Set for the assembly as EXTERNAL (or whatever it
is)
These things havent helped
A huge thank you to anyone who can tell me how to unprotect me crap :-)
Thanks gain

Using the connection object shouldn't be a problem. The error you're
getting looks like it has something to do with UI, in other words are
you trying to do a Console.WriteLine or something similar?
If you post your code for the method it'll be easier for us to see
what's wrong.Anyway, below follows some code snippets for the
connection:
public static void GetData() {
SqlConnection conn = new SqlConnection("Context Connection=true");
conn.Open();
SqlCommand cmd = conn.CreateCommand();
cmd.CommandText = "Select some data from somewhere";
SqlContext.Pipe.ExecuteAndSend(cmd);
}
Notice that in the code above it is not entirely necessary to use the
connection at all, as you are calling ExecuteAndSend on the SqlPipe
class.
