Use UserManger to get.

Like UserManger<ApplicationUser> where ApplicationUser class would be like this.

public class ApplicationUser : IdentityUser
{
    [Required]
    public override string UserName { get; set; }
    [Required]
    public override string Email { get; set; }
    [Required]
    public override string PhoneNumber { get; set; }
    public string Address { get; set; }
    [Required]
    public bool IsActive { get;set; }
    [Required]
    public DateTime PwdExpiryDt { get; set; }
    [Required]
    public bool PwdExpiryFlg { get; set; }
    [Required]
    public DateTime LastPwdChgDt { get; set; }
    [Required]
    public DateTime CreatedDt { get; set; }
    [Required]
    public DateTime ModifiedDt { get; set; }
    [Required]
    public string CreatedBy { get; set; }
    [Required]
    public string ModifiedBy { get; set; }
}

Use _userManager like this

private readonly UserManager<ApplicationUser> _userManager;

Add role to user like this

IdentityResult identityResult = await _userManager.AddToRoleAsync(user, applicationRole.Name);

In your case, you can use RoleManger also.

private readonly RoleManager<ApplicationRole> _roleManager;

var role = _roleManager.Roles.Single(r => r.Name == existingRole)

Role class would be like this.

public class ApplicationRole : IdentityRole
{
    public string Description { get; set; }
    public DateTime CreatedDate { get; set; }
    public string CreatedBy { get; set; }
    public string IPAddress { get; set; }
}
