Injecting IHttpContextAccessor into ApplicationDbContext ASP.NET Core 1.0

@Nkosi has the correct answer but please note that IHttpContextAccessor is now under the namespace:

Microsoft.AspNetCore.Http;

And no longer under:

Microsoft.AspNet.Http;

Try injecting the IHttpContextAccessor Interface

You can even abstract it further by creating a service to provide just the information you want (Which is the current logged in username)

public interface IUserResolverService {
    string GetUser();
}

public class UserResolverService : IUserResolverService {
    private readonly IHttpContextAccessor accessor;
    public UserResolverService(IHttpContextAccessor accessor) {
        this.accessor = accessor;
    }

    public string GetUser() {
        var username = accessor?.HttpContext?.User?.Identity?.Name ;
        return username ?? "unknown";
    }
}

You need to setup IHttpContextAccessor now in Startup.ConfigureServices in order to be able to inject it:

services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
//OR
//services.AddHttpContextAccessor();
services.AddTransient<IUserResolverService, UserResolverService>();

and pass that to your repository as needed to record associated username
