Error Description:
This case resolved by doing the following steps:
1.In class Program.cs Replace this code
IdentityBuilder identityBuilder = builder.Services.AddIdentityCore<User>(pass =>
{
pass.Password.RequireDigit = true;
pass.Password.RequiredLength = 8;
pass.Password.RequireNonAlphanumeric = true;
pass.Password.RequireUppercase = true;
pass.Password.RequireLowercase = true;
pass.User.RequireUniqueEmail = true;
});
With:
IdentityBuilder identityBuilder = builder.Services.AddIdentity<User, Role>(pass =>
{
pass.Password.RequireDigit = true;
pass.Password.RequiredLength = 8;
pass.Password.RequireNonAlphanumeric = true;
pass.Password.RequireUppercase = true;
pass.Password.RequireLowercase = true;
pass.User.RequireUniqueEmail = true;
}).AddEntityFrameworkStores<DataContext>()
.AddDefaultTokenProviders();
