[Mono-list] library

[matterac]

Hi,
I've installed Mono on cygwin and now I'm trying to run some simple application I've made under .NET, some run without problem but other can't run and can't compile, 

this is a problem:

$ ./mcs /t:library tableclass.cs
tableclass.cs(26) error CS0246: Cannot find type `DataTable'
Compilation failed: 1 error(s), 0 warnings

and in other application 

routeserver.cs(21) error CS0246: Cannot find type `TcpServerChannel'
Compilation failed: 1 error(s), 0 warnings


serversip.cs(43) error CS0246: Cannot find type `TcpClientChannel'
Compilation failed: 1 error(s), 0 warnings

I use System.Data & System.Runtime.Remoting.Channel.Tcp

and I find them in mono library

How can I do?
Regards
