How to setup AutoMapper in ASP.Net Core 6

install package

• dotnet add package AutoMapper.Extensions.Microsoft.DependencyInjection

in Program.cs

builder.Services.AddAutoMapper(AppDomain.CurrentDomain.GetAssemblies());

create MappingProfiles.cs

namespace XXX.XXX.Helpers;

public class MappingProfiles: Profile {
    public MappingProfiles() {
        CreateMap<Address, AddressDto>();
    }
}

For those who didn't know like me.

1. Install AutoMapper extension for DI via NuGet or by dotnet add package AutoMapper.Extensions.Microsoft.DependencyInjection
2. Then in the Program.cs file register the service with: builder.Services.AddAutoMapper(typeof(<name-of-profile>)); (In .NET 6 we no longer have the StartUp.cs)

I used Profiles to do my mapping configuration. Here's a link from Automapper about profiles.

Use this line to fix:

builder.Services.AddAutoMapper(typeof(Program));

AutoMapper.Extensions.Microsoft.DependencyInje The display is deprecated

Try to add this line of code in your Program.cs.

services.AddAutoMapper(Assembly.GetExecutingAssembly());

Install AutoMapper Package(version as per your proj requirement)

Install-Package AutoMapper.Extensions.Microsoft.DependencyInjection -Version 9.0.0

after that register a service in CinfigureServices on Startup.cs

using AutoMapper;
public void ConfigureServices(IServiceCollection services){
    services.AddAutoMapper(typeof(Startup));
}
