Hi Guys,

Could anyone one me with Error "No IUserTokenProvider is registered" using ASP.NET Identity, Basically i have to send a user a reset password link. Below is my code

    {
        if(IsValid)
        {
            //var manager = new UserManager();
            //ApplicationUser user = manager.FindByEmail(Email.Text);

            //string code = manager.GeneratePasswordResetToken(user.Id);

          // var manager =  Context.GetOwinContext().GetUserManager<ApplicationUserManager>();           

            var manager = new UserManager();
            ApplicationUser user = manager.FindByEmail(Email.Text);

            string code = manager.GeneratePasswordResetToken(user.Id); Error
            //string callbackUrl = IdentityHelper.GetResetPasswordRedirectUrl(code, Request);
            //var callbackUrl = Url.Action("ResetPassword", "Account", new { userId = user.Id, code = code }, protocol: Request.Url.Scheme);
           // return View();

Hi Shabbir,

You have to specify a UserTokenProvider to generate a token:

using Microsoft.Owin.Security.DataProtection;
using Microsoft.AspNet.Identity.Owin;
// ...

var provider = new DpapiDataProtectionProvider("Sample");
var userManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>());
userManager.UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser>(provider.Create("EmailConfirmation"));

Hi Shabbir,

I have removed Identity.Config and Identity.Models in to seperate project and Name as Identity.cs

So, you could put the code in Identity.cs file.

            var userManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>());
            userManager.UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser>(provider.Create("EmailConfirmation"));

Hi Shabbir,

IUserTokenProvider by default is inserted by OWIN, but when you resolve UserManager from your code, component that provides IUserTokenProvider is not available and this component is not initialised.

You'll have to assign token provider to a global static variable when it is available and then re-use it in UserManager constructor:

Thanks Candice

I tried your link but i am getting an error as 

Error 2 Cannot implicitly convert type 'Microsoft.AspNet.Identity.Owin.DataProtectorTokenProvider<TestLogin.ApplicationUser,System.Guid>' to 'Microsoft.AspNet.Identity.IUserTokenProvider<TestLogin.ApplicationUser,string>'. An explicit conversion exists (are you missing a cast?) c:\inetpub\wwwroot\testlogin\app_code\identitymodels.cs 48 41 http://localhost/TestLogin/

  var dataProtectorProvider = Startup.DataProtectionProvider;
            var dataProtector = dataProtectorProvider.Create("My Asp.Net Identity");
            manager.UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser,Guid>(dataProtector); //Error

Please could you help me with this

Thanks,

Hi Shabbir,

Based on your error, it occurs when you assign a variable of one type to a variable of a different type.

In the IdentityConfig.cs file, we find an ApplicationUserManager class, which contains code commonly called by our application to, well, manage users and behaviors. we will replace the existing code with the following, which essentially expresses ApplicationUserManager in terms of integer keys, and our new custom UserStore. If you look closely, we have added an int type argument to many of the method calls.

var dataProtectionProvider = options.DataProtectionProvider;
  
if (dataProtectionProvider != null)
{
     // *** ADD INT TYPE ARGUMENT TO METHOD CALL:
     manager.UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser, int>(
                    dataProtectionProvider.Create("ASP.NET Identity"));
}
