如何在.NET Core 2.0中使用PrincipalContext

我已經在.NET Core 2.0中創建了一個Web應用程序，我希望使用名稱空間System.DirectoryServices.AccountManagement中的PrincipalContext。如何在.NET Core 2.0中使用PrincipalContext

我想驗證用戶agains的Active Directory這樣的：

private static ClaimsIdentity ValidateUser(string userName, string password) 
     { 
      var domain = GetDomainByLogin(userName); 

      using (var pc = new PrincipalContext(ContextType.Domain, domain, null, ContextOptions.Negotiate)) 
      { 
       if (!pc.ValidateCredentials(userName, password)) return null; 

       var user = UserPrincipal.FindByIdentity(pc, IdentityType.SamAccountName, userName); 
       if (user == null) 
       { 
        throw new Exception(UserNotFound); 
       } 

       var id = new ClaimsIdentity(); 

       id.AddClaim(new Claim(JwtClaimTypes.Subject, userName)); 
       id.AddClaim(new Claim(JwtClaimTypes.Name, userName)); 

       var groups = user.GetGroups(); 
       var roles = groups.Select(x => new Claim(JwtClaimTypes.Role, x.Name)); 

       id.AddClaims(roles); 

       return id; 
      } 
     }

我怎樣才能在PrincipalContext（System.DirectoryServices.AccountManagement）在.NET Core 2.0使用？
