var userManager = serviceProvider.GetRequiredService<UserManager<ApplicationUser>>();
// do whatever
}
private readonly IServiceProvider serviceProvider;
...
A third strategy based on manual or automated ...insertion of dependencies... exists as well:...public interface ISomeService
{
// Interface members
}
public class SomeService : ISomeService
{
public SomeService(DbContext dbContext)
{
DbContext = dbContext;
}
private DbContext DbContext { get; }
}
...Then, ...SomeSe...
