    Using classic ObjectScope I have the following problem.

    At some point
    is used. According to documentation it is obsolete and CreateEntityInstance(context) should be used instead. But how is it possible to get a OpenAccessContextBase from ObjectScope? Best regards Wolfgang

    Hello Wolfgang,

     You cannot get an OpenAccessContextBase from an ObjectScope. Both are wrappers around a lower layer object. But what you can do is use the following code to create an instance of a type.

    var persistentTypeDescriptor = scope.PersistentMetaData.GetPersistentTypeDescriptor(typename);
    var instance = persistentTypeDescriptor.CreateInstance(idValue);

    If the id value is backend calculated you can pass a 'null' value.
    The above code essentially does the same thing as MetaPersistentType.CreateEntityInstance.
