adding into baseline topology

[Som Som]

i am trying to add node into baseline topology:

using (var ignite = Ignition.StartFromApplicationConfiguration())

            {

                var baselineTopology =
ignite.GetCluster().GetBaselineTopology();

                var node = ignite.GetCluster().GetNode(Guid.Parse(
"344BEAA8-4E59-4673-8397-858AB919B895"));

                baselineTopology.Add(node);

               ignite.GetCluster().SetBaselineTopology(baselineTopology);

                ignite.GetCluster().SetActive(true);

                }


But it does not work because node 344be... still not in baseline topologi.
What am i doing wrong?
