Hi Jochen

In addition to the answer of Ive, the ProfileManagerHelper is obsolete starting from 10.0.8 (Feature release) /10.1.0 (Main release). Instead, there is a ProfileHelper that you can use to search in a similar way:

var profileHelper = new ProfileHelper(engine.SendSLNetMessages);

var nameToSearch = "ProfileInstanceName";

var retrievedProfileInstances = profileHelper.ProfileInstances.Read(ProfileInstanceExposers.Name.Equal(nameToSearch));
