Bot Skype membantu kesalahan .NET [duplikat]

Saya mencoba membuat bot skype yang secara otomatis mengirimkan kembali pesan setiap kali kata kunci tertentu dikirim. Tampaknya berfungsi dengan baik di MVS tetapi ketika saya benar-benar menjalankannya, saya mendapatkan kesalahan ini Pengecualian yang tidak tertangani telah terjadi di aplikasi Anda;

************** Exception Text **************
