How to fix identity error?

Question

ASP.NET

added service

services.AddIdentity<IdentityUser, IdentityRole>(options => options.SignIn.RequireConfirmedAccount = true) 
        .AddEntityFrameworkStores<ApplicationDbContext>();

instead of:

services.AddDefaultIdentity<IdentityUser>(options => options.SignIn.RequireConfirmedAccount = true)
        .AddEntityFrameworkStores<ApplicationDbContext>();

so that I could use UserManager. but errors rained down, how to fix it?

Answer 1

The error is well described. Embedded IoC cannot resolve IEmailSender. It's ok, it doesn't have a default implementation. Stick a plug in there and you'll be happy.
