Trying to add AutoMapper to Asp.net Core 2?

Question

I worked on a asp.net core 1.1 project a while ago and use in projetc AutoMapper.

in asp.net core 1.1, I add services.AddAutoMapper() in startup file :

StartUp file in asp.net core 1.1:

    public void ConfigureServices(IServiceCollection services)
    {
        //Some Code

        services.AddMvc();
        services.AddAutoMapper();
    }

And I use AutoMapper in Controller easily.

Controller :

 public async Task<IActionResult> AddEditBook(AddEditBookViewModel model)
 {
    Book bookmodel = AutoMapper.Mapper.Map<AddEditBookViewModel, Book>(model);
    context.books.Add(bookmodel);
    context.SaveChanges();
 }

And everything was fine. But I'm currently working on a Asp.net Core 2 project and I get the error with services.AddAutoMapper() in sturtap file.

Error CS0121 The call is ambiguous between the following methods or properties: 'ServiceCollectionExtensions.AddAutoMapper(IServiceCollection, params Assembly[])' and 'ServiceCollectionExtensions.AddAutoMapper(IServiceCollection, params Type[])'

What is the reason for this error? Also, services.AddAutoMapper in asp.net core 2 has some parameters. what should I send to this parameter?

If you are using AspNet Core 2.2 and AutoMapper.Extensions.Microsoft.DependencyInjection v6.1 You need to use in Startup file

services.AddAutoMapper(typeof(Startup));
