AutoMapper: create instance of destination type if source == null

Is it possible to configure AutoMapper to return a new instance of the destination type if the source object is null?

Source source = null;
Dest d1 = AutoMapper.Mapper.Map<Source, Dest>(source);
// d1 == null

// I'm looking for a way to configure AutoMapper to
// eliminate this code:
Dest d2 = AutoMapper.Mapper.Map<S开发者_如何学Pythonource, Dest>(source) ?? new Dest();

Answering my own question (partially):

AutoMapper has a configuration property named AllowNullDestinationValues which is set to true by default. By setting this to false, I get the behavior shown in the question, e.g:

Mapper.Configuration.AllowNullDestinationValues = false;

//...

Source source = null;
Dest d = AutoMapper.Mapper.Map<Source, Dest>(source);
// d is now a new instance of Dest

This solution works OK for simple types, where source and destination types map well. I still have some issues with complex mappings (I will update the question to show an example).

You can also use .NullSubstitute() to replace NULL value to some custom value for any property in Automapper, e.g.:

CreateMap<SMModel, VM_SMModel>()
                    .ForMember(d => d.myDate, o => o.NullSubstitute(new DateTime(2017,12,12)));
