Hello,

Im studying Openness, the document show can access PLC service - crossreference, i tried put demo code to visual studio, but meet error:  CS0246: the type or namespace name ‘CrossReferenceService’ could not be found…

PlcSoftware plcSoft = (PlcSoftware)softTarget;
PlcBlockSystemGroup blockComposition = plcSoft.BlockGroup;
PlcBlockComposition blockFolder = blockComposition.Blocks;
PlcBlock mainBlock = blockComposition.Blocks.Find("Main");
if (mainBlock != null)
{
try
{
CrossReferenceService crossReferenceService =
mainBlock.GetService<CrossReferenceService>();

}
catch (Exception e)
{
Console.WriteLine(e.Message);
}}}

but i already add reference about Siemens.Engineering:

do you meet same problem?

Also, is there any more manual/document for openness development?
