How to use UserManager in my controller?

What the title says, what I'm doing currently:

private  SignInManager<IdentityUser> _signInManager;
private  UserManager<IdentityUser> _userManager;

public UtilizadoresController(ApplicationDbContext context, SignInManager<IdentityUser> signInManager, UserManager<IdentityUser> userManager)
{
    _context = context;
    _signInManager = signInManager;
    _userManager = userManager;
}

private  SignInManager<IdentityUser> _signInManager;
private  UserManager<IdentityUser> _userManager;

public UtilizadoresController(ApplicationDbContext context, SignInManager<IdentityUser> signInManager, UserManager<IdentityUser> userManager)
{
    _context = context;
    _signInManager = signInManager;
    _userManager = userManager;
}

But Visual Studio doesn't recognize the UserManager<IdentityUser> type:


'UserManager<>' is an ambiguous reference between 'Microsoft.AspNet.Identity.UserManager<TUser>' and 'Microsoft.AspNetCore.Identity.UserManager<TUser>'

When I change it to private Microsoft.AspNet.Identity.UserManager<IdentityUser> _userManager; I get this error: 'Microsoft.AspNetCore.Identity.IdentityUser' cannot be used as type parameter 'TUser' in the generic type or method 'UserManager<TUser>'. There is no implicit reference conversion from 'Microsoft.AspNetCore.Identity.IdentityUser' to 'Microsoft.AspNet.Identity.IUser<string>'.

Try IdentityUser<string> maybe?

As in private IdentityUser<string> _userManager; ?

Angius•2y ago

Yeah And in the constructor

GipperOP•2y ago

it builds, but then when I go to the view I get:

InvalidOperationException: Unable to resolve service for type 'Microsoft.AspNetCore.Identity.IdentityUser`1[System.String]' while attempting to activate 'Trabalho_Lab_Aplicações_Web.Controllers.UtilizadoresController'.

Huh Not sure, then I wonder if you need to create your own user type...? Probably not Ah, wait UserManager<IdentityUser<string>> not just IdentityUser<string>

GipperOP•2y ago

Get the same ambiguous reference error from before. Could it be soething wrong in the Program.cs?

Angius•2y ago

Not sure tbh

GipperOP•2y ago

I removed the ambiguity by changing it to Microsoft.AspNetCore.Identity.UserManager<IdentityUser<string>> and now it seems to be working, at least the instance of that objet recognizes a changepasswordasync method

Angius•2y ago

Ah, nice

GipperOP•2y ago

Still get the invalid exception tho on the view

Angius•2y ago

What invalid exception?

Huh At this point, I'd just create a new Razor Pages project with scaffolded Identity and see how they do it

GipperOP•2y ago

Fixed it, I think. It was the program.cs where for some reason I had a call to AddDefaultIdentity instead of just AddIdentity

GipperOP•2y ago

The controller at least constructs fine now even with usermanager and signinmanager
