How to create custom URI for application?

Question

C++ / C#

Good afternoon.
I want to add the ability to respond to a click on a link in my application.
For example, the way Skype implemented it:
<a href="skype:echo123?call">...</a>
The application itself in C #, created using Visual Studio 2010. All my attempts to find documentation rested on the official MS website, but they used a bunch of windows 8 and the application store, which is not suitable for other versions of Windows.

Answer 1

Registering an Application to a URL Protocol

Answer 2

You need to edit the registry. Then, with such a link, the string "echo123? call" will be transmitted to the application

Answer 3

it?
