Keterangan
Metode DeleteProfile menghapus semua informasi profil dan properti untuk profil pengguna untuk yang ditentukan username
dari sumber data untuk yang ditentukan ApplicationName.

Untuk menghapus properti profil yang dikelola oleh penyedia profil selain penyedia default, dapatkan referensi ke penyedia profil menggunakan Providers properti dan panggil DeleteProfiles metode penyedia secara langsung.
