c# - クロス REST サービス

Question

以下では、1 つの学生/グループ サービスを実行していますが、ここでは、「グループ」を保持するサービスと「学生」を保持するサービスの 2 つのサービスを実行したいと考えています。しかし、生徒をグループに追加したいときに混乱が生じます。どうすればよいcross serviceですか?

たとえば、このコードは学生をグループに追加し、残りの Web サービスはすべて 1 つにします。

    public void AddStudentToGroup(string group, string studentID, string firstName, string lastName)
    {
        var result = Groups.Where(n => String.Equals(n.GroupName, group)).FirstOrDefault();
        var result1 = students.Where(n => String.Equals(n.StudentID, studentID)).FirstOrDefault();
        if (result != null)
        {
            result.Groupsz.Add(new Student() { StudentID = studentID, FirstName = firstName, LastName = lastName });
        }
        if (result1 != null)
        {
            result1.StudentGroup.Add(new Group() { GroupName = group });
        }

    } 

したがって、私の質問は、サービスをグループを保持するサービスと学生を保持するサービスの 2 つに分割した場合、上記のコードで行ったこと (グループに学生を追加する) を 2 つのサービスにまたがって達成するにはどうすればよいかということです。そして、これを達成しようとして、クライアントはどこに POST しますか?

私の 1 つのサービス全体は以下のコードのように見えますが、グループを取り出して学生情報のみを残し、グループを独自の安らかな Web サービスに変えることを考えています。上記を達成しようとしているときに、あるサービスから別のサービスにどのように通信するのかわかりませんか?
