Next, we will add a controller, which will derive from our custom BaseController class.

The following is the code of ServiceRequestController, which contains an HTTP POST method to save the service requests of the tenant:

    [LoggingActionFilter] 
    [Route("api/[controller]")] 
    public class ServiceRequestController : BaseController 
    { 

        IServiceRequestManager _manager; 
        ILogger<ServiceRequestController> _logger; 

        public ServiceRequestController(IServiceRequestManager
        manager, ILogger<ServiceRequestController> logger) :
          base(manager, logger) 
        { 
            _manager = manager; 
            _logger = logger; 
        } 
        [HttpGet] 
        public IEnumerable<TenantServiceRequest> GetTenantsRequests() 
        { 
            return _manager.GetAllTenantServiceRequests(); 
        } 

        [TransactionActionFilter()] 
        [HttpPost] 
        public void Post(ServiceRequest serviceRequest) 
        { 
            try 
            { 
                _manager.Create(serviceRequest); 
            } 
            catch (Exception ex) 
            { 
                throw LogException(ex); 
            } 

        } 
    }

Given next is our Startup class, which registers all the dependencies in the ConfigureServices method:

    public void ConfigureServices(IServiceCollection services) 
    { 

        services.AddScoped<IUnitOfWork, UnitOfWork>(); 
        services.AddScoped<IDbFactory, DbFactory>(); 
        services.AddScoped<DataContext>();        
        services.AddScoped<IRepository, Repository>(); 
        services.AddScoped<IServiceRequestManager,
          ServiceRequestManager>(); 
        services.AddScoped<ITenantManager, TenantManager>(); 
        services.AddScoped<BusinessManagerFactory>(); 
        // Add framework services. 
        services.AddMvc(); 

    }

And here is the Configure method:

    public void Configure(IApplicationBuilder app,
      IHostingEnvironment env, ILoggerFactory loggerFactory) 
      { 
        loggerFactory.AddConsole(LogLevel.Information); 
        loggerFactory.AddDebug(); 

        app.UseMvc(); 

      }
