(C# UWP/WinRT) FTPS with Client Cert from Windows Certificate Store

Demonstrates how to do mutual TLS authentication using a client certificate installed in the Windows certificate store.

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// If using implicit TLS, you probably want port 990..
ftp.Port = 990;

// Set this to false for implicit TLS, otherwise set to true for explicit TLS (where port is typically 21).
ftp.AuthTls = false;

// Set this to true for implicit TLS, otherwise set to false.
