How can I run a windowed application on another user's desktop?

Question

C++ / C#

The task is as follows: on the terminal server in an administrator session, a server written in C # is running. Is it possible somehow with the help of ProcessStartInfo or in some other way that this server would run a certain application on the desktop in another user's session?

Answer 1

It is possible, but if that user has a client application that listens to commands from your server.
It is logical that someone should execute the command, nothing will happen by itself.
