I managed to compile it
Nice to hear that you were successful.
I also added the HeightFieldCollision feature
This is interesting. Some years ago I missed this feature.
I would gladly post it in here if I knew how
This would be nice. Aside the binaries you should publish the updated code.
You can upload it to your private BitBucket account and then create a pull request to the official repository.
If you don't have a BitBucket account yet, just create it. It's very easy. Then create a new repository and tell the wizard point to the official repository.
compiled against newton 2.35
The latest binary version of Newton 2 seems to be 2.36.
Changelog: Minor buf fixes on ray cast and in capsule and cone shapes. Also last public realease of core 200.

Sadly [...] they dropped the Vehicles support with Newton 2 [...].
I guess it's possible to do it in other ways, but I couldn't find any explanation or even a hint/lead about what those ways are.
Did you look to the forum of the Newton community?
When I had problems and requests, I got good support.
If you don't find useful information there, don't be afraid to create a new topic.
By the way: The Newton author (Julio Jerez) published the Newton source code. So in general it could be possible to (re-)add missing features.
It would be interesting, why the vehicle class was removed. Perhaps there are discussions about in the forum.
The Newton forum you find here: http://newtondynamics.com/forum/index.php
I tried to create my own C# Vehicle class as part of my project code [...] but I have almost no knowledge about physics
Nice idea, but it's not easy to create a vehicle dynamics model. I created a simple model for an underwater vehicle with the application Matlab/Simulink. A team mate created a more complex model for an off-the-road vehicle, which tooks several weeks for a realistic looking behaviour.
I think this sub forum (with only a few active members) is no good place for asking for this topic.
My suggestions: Search in (or ask in) the Newton forum and a game developer forums. Possibly you get links to related open source projects. (I suppose you already searched by Google.)
