The Runtime.Deployment namespace shadowed the Deployment EF entity type for every file under ZB.MOM.WW.OtOpcUa.Runtime.Tests.*: C# name lookup walks the enclosing namespace chain and finds the namespace before a using-imported type, so 19 pre-existing call sites failed with CS0118. Caught only by a full-solution build - the Host and its own tests compiled fine.
