Ignore a property in AutoMapper?

I use this extension method:

public static IMappingExpression<TSource, TDestination> IgnoreMember<TSource, TDestination>(
    this IMappingExpression<TSource, TDestination> map, Expression<Func<TDestination, object>> selector)
{
    map.ForMember(selector, config => config.Ignore());
    return map;
}

and I use it like this

Mapper.CreateMap<MyType1, MyType2>().IgnoreMember(m => m.PropertyName);

Hope that helps.

On your Mapper.CreateMap<Type1, Type2>() you can use either

.ForSourceMember(x => x.Id, opt => opt.Ignore())

or

.ForMember(x => x.Id, opt => opt.Ignore())

UPDATE: It seems like .Ignore() is renamed to .DoNotValidate() according to the AutoMapper docs.
