Rewrite VisualBasic Windows VPN Client in C# and create a new GUI

Hey there!

First of all, you need to add the word 'VPN' to your application for this job, otherwise, it will be ignored!

We have a legacy 'WindowsForm' VPN client written in VisualBasic (we have the source code), that we would like to upgrade and update the visual feel of it to today's standards.

The source code should be rewritten in C#, and the GUI created with 'WPF' with the usual Model, View, ViewModel architecture.

This means that we do not need you to develop any new functionality to the core app, just convert the VB parts to C# and create a new GUI upon it.

You will be given examples of how the new GUI should look like. But the rule of thumb is the modern look of the big VPN providers.

A secondary objective is to test the windows app to see if the tun/tap behaves correctly on windows 7/10.

Knowledge about OpenVPN, and windows tun/tap is recommended as well!

I will let this run for 2 days to get everyone a chance to bid.

Skills: C# Programming, C++ Programming, Software Architecture, Visual Basic, WPF
