OK, well - converting an app from an RDBMS solution to a Graph one is something I've done in the past - so first off - it is totally doable, and totally worth it.
The downside is that generally you can't do a straight 'swap' - it's important to think about the model in the graph that you want to work with - and I think you'll find that easier by swapping to the official .NET driver. Which is dependent on what you're coding in - as in - what version of .NET you're compiling with, and what version of Neo4j you intend to target.
What I would suggest is taking a bit of your code - maybe something like a 'user creation' section and write it using the
Start small, see how it works - that's the best advice I can give.
Obviously - if you have trouble - ask and we can see what we can do!
All the best
