Kimlik doğrulamasını ayarlama

İstemci kitaplıklarını kullandığınızda kimlik doğrulamak için Uygulama Varsayılan Kimlik Bilgileri (ADC)'ni kullanırsınız. ADC'yi ayarlama hakkında bilgi edinmek için Uygulama Varsayılan Kimlik Bilgileri için kimlik bilgileri sağlama bölümüne bakın. ADC'yi istemci kitaplıklarıyla kullanma hakkında bilgi edinmek için İstemci kitaplıklarını kullanarak kimlik doğrulama başlıklı makaleyi inceleyin.
