AutoMapper Migrating from static API

Question

https://github.com/AutoMapper/AutoMapper/wiki/Migrating-from-static-API

this change breaks my system.

Before update, I use:

===> Startup.cs

public class Startup {     public Startup(IHostingEnvironment env)     {     ...         MyAutoMapperConfiguration.Configure();     } } 

===> MyAutoMapperConfiguration.cs

public class MyAutoMapperConfiguration {     public static void Configure()     {         Mapper.Initialize(a =>         {             a.AddProfile<AbcMappingProfile>();             a.AddProfile<XyzMappingProfile>();             a.AddProfile<QweMappingProfile>();         });     } } 

===> AbcMappingProfile.cs

public class AbcMappingProfile : Profile {     protected override void Configure()     {         Mapper.CreateMap<AbcEditViewModel, Abc>();         Mapper.CreateMap<Abc, AbcEditViewModel>();         ...     } } 

ERROR:

'Mapper.CreateMap()' is obsolete: 'The static API will be removed in version 5.0. Use a MapperConfiguration instance and store statically as needed. Use CreateMapper to create a mapper instanace.'

I can use Mapper.Map. Now How can I use it

Answer 1

Instead of:

Mapper.CreateMap<AbcEditViewModel, Abc>(); 

The new syntax is:

var config = new MapperConfiguration(cfg => {   cfg.CreateMap<AbcEditViewModel, Abc>(); }); 

Then:

IMapper mapper = config.CreateMapper(); var source = new AbcEditViewModel(); var dest = mapper.Map<AbcEditViewModel, Abct>(source);
