Create a secure logon to a RDP server via VPN

I have an application running on a Remote Desktop Server, that is used by lots of different clients on different sites.  To make things a little more secure, we are going to set it so users login to a VPN first and then the Remote Desktop.  I was thinking of writing a small C# application to control this and provide clients with an installer, that they run on each machine.  The settings will be entered into the application - and off they go (hopefully).

I'm only just getting to grips with c# and want to know if c#/.net will allow me to do this - with a pretty basic knowledge.

  • Enter / store settings for VPN and RDP login
  • Login to VPN
  • If successful, login to RDP
  • Disconnect from VPN when RDP is disconnected.

You should be aware that in today's world, a correct implementation of user workstation SHOULD NOT allow installation of ANYTHING.
Even at home, you should setup the workstation as you like with admin account, lock it down and create a regular user account to run things. This approach, according to Microsoft will reduce attack surface by up to 96%.
Therefore installation of that software might not work.

You should check some other 3rd party solution to secure RDP access. Instead of VPN, you might want to consider utilizing MFA with a full RDS infrastructure including WEB, Gateway, Broker and HOST. Licensing for RDS also will be required. But that functionality can be deployed on any server in the infrastructure, even AD DC for that matter.
