Automapper 3.2.1 The Call is Ambiguous Between the Following Methods or Properties

Just updated Automapper on my project to 3.2.1. And I got the following error:

Mapper.CreateMap<TaskCreated, Task>()  
.ForMember(x => x.Created, x => x.ResolveUsing(t => DateTime.UtcNow))  
.ForMember(x => x.Modified, x => x.ResolveUsing(t => DateTime.UtcNow))  
.ForMember(x => x.Deleted, x => x.Ignore());  

A quick search finds other people with the same issue.

So there are 2 options.

1. Use MapFrom:
   C#

   Mapper.CreateMap<TaskCreated, Task>()
   .ForMember(x => x.Created, x => x.MapFrom(t => DateTime.UtcNow))
   .ForMember(x => x.Modified, x => x.MapFrom(t => DateTime.UtcNow))
   .ForMember(x => x.Deleted, x => x.Ignore());

2. Explicitly tell Automapper what object I’m using in the lambda:
   C#

   Mapper.CreateMap<TaskCreated, Task>()  
   .ForMember(x => x.Created, x => x.ResolveUsing((TaskCreated t) => DateTime.UtcNow))  
   .ForMember(x => x.Modified, x => x.ResolveUsing((TaskCreated t) => DateTime.UtcNow))
   .ForMember(x => x.Deleted, x => x.Ignore());
