SignedXml not found in .net 2.0 ?

[--- .NET Em ---]

I had a code snippet that worked fine in .NET 1.1 with WSE 1.x. I now
installed Visual C# Express 2005 and .NET Framework 2.0 with WSE 3.0. I am
trying to compile the same class but it cannot find SignedXml.

I have included the System.Security.Cryptography.Xml namespace but the
compiler tells me the Xml namespace cannot be found within
System.Security.Cryptography.

Where has it been moved? according to MSDN documentation it is still there
but I still get an error.

Thanks in advance,
Emilio

Never mind, apparently I was missing the System.Security.DLL reference :-(
