I have created a new video that shows how to create a demo Windows desktop BlackPearl client application using our .NET/C# Software Development Kit (SDK). Anybody can create this client in less than 15 minutes. You do not need an actual BlackPearl gateway, you can use our BlackPearl simulator. And all the other tools you need are free to download. Give it a try.
Here’s the final Visual Studio project files for the demo client that we build.
