[PBKK-3] Media Capture

Pada pertemuan ketiga mata kuliah PBKK kami mendapat tugas untuk membuat aplikasi desktop sederhana menggunakan .NET Framework. .NET Framework adalah platform perangkat lunak yang dikembangkan oleh Microsoft. Frmaework ini digunakan untuk membangun dan menjalankan berbagai jenis aplikasi perangkat lunak di lingkungan sistem operasi Windows. aplikasi yang harus kami buat kali ini adalah membuat aplikasi media capture. Aplikasi ini akan mampu mengaktifkan kamera yang tersedia pada perangkat, menagkap gambar, dan menyimpannya.
