InvalidOperationException: Unable to resolve service for type 'Microsoft.AspNetCore.Identity.IUserStore`1[Microsoft.AspNetCore.Identity.IdentityUser]' while attempting to activate 'Microsoft.AspNetCore.Identity.UserManager`1[Microsoft.AspNetCore.Identity.IdentityUser]'.
public readonly RoleManager RoleManager; public readonly UserManager UserManager; public AdministrationController(RoleManager RoleManager, UserManager UserManager) { this.UserManager = UserManager; this.RoleManager = RoleManager; } you have to add this to the top of your document. It looks like in this tutorial he left out a few things :/

Wessam Elsheikh there are plenty of third party reporting systems. I would look at them. I made the mistake of writing my own that generated HTML and output PDF. I ended up buying dev express the reports took me 1/10th of the time to put together
Is there a way to create an entry (a user) in another Asp.Net Identity Database from another Project other than creating a user in the current Asp.Net Identity? Basically, in my ASP.NET CORE (main) app I want to create some customer users that would be stored in another Identity Database, other than the "ROOT" application - like to say. Thank you!
Hi, Whenever I am calling any method of SignInManager Class. It is throwing an exception: Invalid Object Name 'AspNetUserClaims'. Actually I have not created AspNetUserClaims table while migration as I dont need AspNetUserClaims table. Please can someone help me
How can I validate my Email? I dont have my email on my Model class its the default email from IdentityUser its on AspNetUsers Table, I cannot change it using [Parameters]
it doesnt work at all, asp .net wants default constructor without additional parameters for it. and if i dont create such constructor then i get System.MissingMethodException when i enter View()
do we need to add anything else? I am getting errors when going to the registration page. InvalidOperationException: Unable to resolve service for type 'Microsoft.AspNetCore.Identity.UserManager`1[Microsoft.AspNetCore.Identity.IdentityUser]' while attempting to activate 'Mathly.Controllers.AccountController'. Do i need to provide identtiyUser service on start up or async services
In Startup.cs file, please check if you are passing ApplicationUser type as the generic argument to AddIdentity() method services.AddIdentity(options => { options.Password.RequiredLength = 10; options.Password.RequiredUniqueChars = 3; options.SignIn.RequireConfirmedEmail = true; }) .AddEntityFrameworkStores() .AddDefaultTokenProviders(); In AccountController constructor, please check if ApplicationUser type is passed as the argument to both UserManager and SignInManager. public AccountController(UserManager userManager, SignInManager signInManager, ILogger logger) { this.userManager = userManager; this.signInManager = signInManager; this.logger = logger; } Would love to know if you have managed to fix the error.
Hi Venkat, I don't understand why are we copying the data from the incoming RegisterViewModel object into the IdentityUser object ??? var user = new IdentityUser { UserName = model.Email, Email = model.Email };
RegisterViewModel is a Model class which won't have a table in the database. It will just provide the fields like username or email, password, confirm password, etc. in the form. So if we copy the values from RegisterViewModel it will be easier to use. And somehow I feel like this is a good practice. We should not directly copy data or values into Models that are directly connected to the database. I hope I helped. And if I am wrong please correct me, since I am learning as well. Thank you.
this is creating an enumerator of IdentityUser Type which then gets saves into the database. The enumerator makes is easy for the database to sort and save as a less complex object. Its proper programming technique. You can google enumerators
Hi, I've followed your tutorial through-out and checked my code regularly, I have ran into a issue though. When I press on the "Register" page in the NAV, the following error pops up. An unhandled exception occurred while processing the request. InvalidOperationException: Unable to resolve service for type 'Microsoft.AspNetCore.Identity.UserManager`1[Microsoft.AspNetCore.Identity.IdentityUser]' while attempting to activate 'ProjectApplicationX00140684.Controllers.AccountController'. Microsoft.Extensions.DependencyInjection.ActivatorUtilities.GetService(IServiceProvider sp, Type type, Type requiredBy, bool isDefaultParameterRequired) Any advice on how I could fix this ?
I think I 've run into a similar error, you need to register the services in Startup.cs/ConfigureServices() method: //1- register IdentityDBContext services.AddDbContext(options => options.UseSqlServer( context.Configuration.GetConnectionString("IdentityDBConnection"), x => x.MigrationsAssembly("WebApplication1") ) ); //2- register the defaultIdentity: services.AddDefaultIdentity(options => options.SignIn.RequireConfirmedAccount = true) .AddRoles().AddEntityFrameworkStores();
At 2:33 How and where is this constructor invoked? Someone needs to actually pass this method the UserManager and SignInManager parameters right? How are these parameters passed when the controller is constructed during routing?
Hello Robbe - Great question. Yes, you are right, someone needs to pass instances of UserManager and SignInManager to the controller. With the built-in dependency injection support in .NET core we no longer have to use the new keyword and instantiate the dependencies ourselves. This is automatically done by the built-in dependency injection system in .NET core. We discussed dependency injection in Part 19 of this video series. The following is the link, if you want to check it out.

Thank you for your input. I have a question turns out that I am using identity for user identification. I register my users and log in the first time but when I want to make a new login I get the message Invalid login Attempt. Then finding out I found that it is not allowed as a username because the @ is included, but I want to keep my username as email. Another solution I found but it does not seem the most correct is changing in the database the EmailConfirmed column to true to true. on the other hand probe put in my starup file the following code options.SignIn.RequireConfirmedEmail = true; But neither The problem is that the PasswordSignInAsync method shows as a result Not Allowed can you help me with any solution?
10:01 If someone can get unauthorized access to this table, they probably can get access to other tables, and they wouldn't need to know the passwords anyway because all other data are in plain text! 😂😂😂😂
