user124226: What packages do I need to use for creating Bitcoin HD Wallet in C# using BIP44?
How can I connect to a remote Bitcoin Node to read all the deposit transactions received by various child addresses in the HD Wallet?
Which Node Client can I use for this?

user21478: I advise you just to rely on https://github.com/dgarage/NBXplorer/
This is an API more flexible and more stable than Bitcoin Core to manage HD wallets. There is a C# client, and it integrate nicely with NBitcoin.
You can create PSBTs from it, ready to sign with NBitcoin. (Disclaimer: I am the main maintainer for both NBitcoin and NBXplorer)

In regard to the follow-up questions:

A small multisig wallet example

NBXplorer.Client is the name of the nuget package to call the documented API.
