(C# UWP/WinRT) Create Signed SOAP XML for DIAN Colombia WCF Service

Demonstrates how to create a signed SOAP XML document for DIAN Colombia.

Chilkat Universal Windows Platform (UWP) / WinRT Downloads

Chilkat for the Universal Windows Platform (UWP)

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

// This example will produce a signed SOAP XML message that looks like this:
