creating dll question

[wuhoo]

I have a managed vc++ class which using ADO libraries, for example...

using namespace System::Data;
using namespace System::Data::OleDb;

public __gc class ConfigCheck
{

}


I want to wrap this into a dll.....

when building the dll project I get the following errors...

error C2039: 'Data' : is not a member of 'System'
error C2871: 'Data' : a namespace with this name does not exist
error C2039: 'Data' : is not a member of 'System'
error C2871: 'OleDb' : a namespace with this name does not exist

anyone have any ideas? thanks
