Keterangan

Dalam beberapa kasus, pengguna mungkin tidak memiliki aplikasi yang diinstal untuk menangani file yang Anda luncurkan. Secara default, Windows akan menangani kasus-kasus ini dengan menyediakan tautan kepada pengguna untuk mencari aplikasi yang sesuai di toko. Gunakan LauncherOptions.PreferredApplicationDisplayName bersama dengan LauncherOptions.preferredApplicationPackageFamilyName untuk memberi pengguna aplikasi di Windows Store yang dapat mereka peroleh untuk menangani file. Nama tampilan yang Anda gunakan harus sesuai dengan nama tampilan aplikasi di Bursa Windows.

Anda harus mengatur kedua properti aplikasi pilihan ini untuk merekomendasikan aplikasi. Mengatur satu tanpa yang lain akan mengakibatkan kegagalan.

Catatan

Anda tidak dapat mengatur properti aplikasi pilihan dan URI fallback secara bersamaan, karena hanya satu fallback yang dapat digunakan. LAUNCHER API akan gagal jika kedua fallback diatur.

Penting

Properti ini hanya diimplementasikan pada perangkat Desktop.
