Using AuthP in WebApi is not working showing No service for type 'Microsoft.AspNetCore.Identity.UserManager

[nasir-adappt]

I am trying to implement the AuthP library in my .NET 6 WebApi project. I have used ASP.NET Core Identity for Individual Account security. I have two custom Identity classes which are:
ApplicationUser extended from IdentityUser and
ApplicationRole extended from IdentityRole

Now I have installed the AuthP library in my project and added the below code for configuration:

builder.Services.RegisterAuthPermissions<UserPermissions>(
    options =>
    {
        options.UseLocksToUpdateGlobalResources = false;
    })
    .UsingEfCoreSqlServer(connectionString)
    .IndividualAccountsAuthentication<ApplicationUser>()
    .AddSuperUserToIndividualAccounts<ApplicationUser>()
    .RegisterFindUserInfoService<CustomAccountUserLookup>()
    .AddRolesPermissionsIfEmpty(AppAuthSetupData.RolesDefinition)
    .AddAuthUsersIfEmpty(AppAuthSetupData.UsersRolesDefinition)
    .SetupAspNetCoreAndDatabase(options =>
    {
        //Migrate individual account database
        options.RegisterServiceToRunInJob<StartupServiceMigrateAnyDbContext<ApplicationDbContext>>();
        //Add demo users to the database
        options.RegisterServiceToRunInJob<StartupServicesIndividualAccountsAddDemoUsers>();
    });

But whenever I run the project I get the below error:
No service for type 'Microsoft.AspNetCore.Identity.UserManager`1[Microsoft.AspNetCore.Identity.IdentityUser]' has been registered.

Please help me to solve the problem

Hi @nasir-adappt,

The AuthP library implements its own Roles system - see this article for how this works. That means you don't use the Individual Account security Roles.

You get the error because your individual user accounts database doesn't match the database that the 'Microsoft.AspNetCore.Identity.UserManager expects.

PS. There are some useful documentation on Permissions and AuthP Roles in the Concepts section on the right had side of the AuthP docs.

Hello @JonPSmith , I also have the same problem, what do you mean by the fact that the database does not match???

services.RegisterAuthPermissions(options =>
{
//This tells AuthP that you don't have multiple instances of your app running,
//so it can run the startup services without a global lock
options.UseLocksToUpdateGlobalResources = false;

        //This sets up the JWT Token. The config is suitable for using the Refresh Token with your JWT Token
        options.ConfigureAuthPJwtToken = new AuthPJwtConfiguration
        {
            Issuer = jwtData.Issuer,
            Audience = jwtData.Audience,
            SigningKey = jwtData.SigningKey,
            TokenExpires = new TimeSpan(0, 5, 0), //Quick Token expiration because we use a refresh token
            RefreshTokenExpires = new TimeSpan(1, 0, 0, 0) //Refresh token is valid for one day
        };
    })
    .UsingEfCoreSqlServer(configuration.GetConnectionString("SqlServerConnection")) //NOTE: This uses the same database as the individual accounts DB
    .IndividualAccountsAuthentication<ApplicationUser>()
    .AddSuperUserToIndividualAccounts<ApplicationUser>()
    .RegisterFindUserInfoService<CustomUserLookup>()
    .AddRolesPermissionsIfEmpty(AppAuthSetupData.RolesDefinition)
    .AddAuthUsersIfEmpty(AppAuthSetupData.UsersRolesDefinition)
    .SetupAspNetCoreAndDatabase(options =>
    {
        options.RegisterServiceToRunInJob<StartupServiceMigrateAnyDbContext<IdentityLocalDbContext>>();
        options.RegisterServiceToRunInJob<StartupServicesIndividualAccountsAddDemoUsers>();
    });

    services.AddScoped<IAddNewUserManager, IndividualUserAddUserManager<ApplicationUser>>();

System.InvalidOperationException: 'No service for type 'Microsoft.AspNetCore.Identity.UserManager`1[Microsoft.AspNetCore.Identity.IdentityUser]' has been registered.'

hi @raulidavid,

I assume you get this exception on startup so the IndividualUserAddUserManager<ApplicationUser> doesn't match to what it expected. I can't be exactly sure why, but maybe your ApplicationUser doesn't match the IdentityUser class.

Try comment out the services.AddScoped<IAddNewUserManager, IndividualUserAddUserManager<ApplicationUser>>(); and check it works without that service.

PS. The Example3.MvcWebApp.IndividualAccounts's Program uses the IndividualUserAddUserManager and works, so have a look if anything else is different in that project.

Thanks @JonPSmith I was able to solve it
