I am facing Unable to resolve service for type 'Microsoft.AspNetCore.Identity.RoleManager` problem in my Administration controller here is how I injected RoleManager in Administration Controller
private readonly RoleManager<IdentityRole> roleManager;
private readonly UserManager<ApplicationUser> userManager;
public AdministrationController(RoleManager<IdentityRole> roleManager,UserManager<ApplicationUser> userManager)
{
this.roleManager = roleManager;
this.userManager = userManager;
}
And in my startup.cs file I have added Identity service like this
services.AddIdentity<ApplicationUser, IdentityRole<int>>()
.AddEntityFrameworkStores<CISContext>()
.AddDefaultTokenProviders();
As you can see while adding Identity service in my startup.cs file I have added datatype in my IdentityRole class in order to change the datatype of AspNetUsers Id column from string to int
How can I solve this Issue please?
Just a hunch, because I haven't tested this and haven't worked with roles for a while, but have you tried to specify the generic type parameter while injecting it?
I.e. RoleManager<IdentityRole<int>> roleManager.
Because I noticed that you're adding it in startup.cs by specifying a non-default int key type.
