Project DateTime to DateTimeOffset?

[cheng93]

Source/destination types

using System;
using System.Linq;
using AutoMapper;
using AutoMapper.QueryableExtensions;

var mapping = new MapperConfiguration(x =>
{
    x.CreateMap<Foo, Bar>();
});

var foos = Enumerable.Empty<Foo>();

var mapped = foos.AsQueryable().ProjectTo<Bar>(mapping);

Console.WriteLine(mapped.Count());

public class Foo
{
    public int Id { get; set; }

    public DateTime ShiftStart { get; set; }

    public DateTime ShiftEnd { get; set; }
}

public class Bar
{
    public int Id { get; set; }

    public DateTimeOffset? ShiftStart { get; set; }

    public DateTimeOffset? ShiftEnd { get; set; }
}

Mapping configuration

Version: x.y.z

10.1.1

Expected behavior

This works with 10.0.0

Actual behavior

Unhandled exception. AutoMapper.AutoMapperMappingException: Unable to create a map expression from Foo.ShiftEnd (System.DateTime) to Nullable`1.ShiftEnd (System.Nullable`1[System.DateTimeOffset])

Mapping types:
Foo -> Bar
Foo -> Bar

Type Map configuration:
Foo -> Bar
Foo -> Bar

Destination Member:
ShiftEnd

Steps to reproduce

// Your calls to Mapper.Map or ProjectTo here, with source/destination objects constructed

I don't think this needs to be a built in conversion. Just add the needed map.

[cheng93]

Oh right, so adding x.CreateMap<DateTime, DateTimeOffset?>(); does fix it.

Just odd that a minor release broke existing functionality

[lbargaoanu]

That's because it worked by accident.
