• DataSourceAttribute - Define a Data Source

  [assembly: DataSource(
    typeof(Saraff.Twain.DS.Screen.ScreenDataSource),
    Country = TwCountry.BELARUS,
    Language = TwLanguage.RUSSIAN,
    MaxConnectionCount = 64,
    IdentityProvider = typeof(_IdentityProvider))]
  

  A _IdentityProvider class must implement a IIdentityProvider interface. See follow sample:

  internal sealed class _IdentityProvider:IIdentityProvider {
  
    public Identity Identity {
        get {
            return new Identity {
                Company="asdf",
                ProductFamily="zcvx",
                ProductName="wert",
                Version=new Version(4,5)
            };
        }
    }
  }
