Net Core Dependency Injection for Non-Controller

Question

Seems crazy that something like this is causing me such a headache. But here it is:

How do you use the built-in dependency injection for net core for a non-controller class? Please provide an example with includes instantiation.

Thanks.

Answer 1

Just make the class a service.

In startup.cs

services.AddScoped<AccountBusinessLayer>(); 

Then in controller, same as you do for other services:

private readonly AccountBusinessLayer _ABL; 

Include in constructor as you do for other services:

 public AccountController(     UserManager<ApplicationUser> userManager,     SignInManager<ApplicationUser> signInManager,IOptions<IdentityCookieOptions> identityCookieOptions,     IEmailSender emailSender,     ISmsSender smsSender,     ILoggerFactory loggerFactory,     RoleManager<IdentityRole> roleManager,     AccountBusinessLayer ABL   ) {   _userManager = userManager;   _signInManager = signInManager;   _externalCookieScheme = identityCookieOptions.Value.ExternalCookieAuthenticationScheme;   _emailSender = emailSender;   _smsSender = smsSender;   _logger = loggerFactory.CreateLogger<AccountController>();   _roleManager = roleManager;   _ABL = ABL; }
