Properly reading a message body with a Transport Agent in an Exchange plugin

While it doesn't look that complicated in the first place, properly reading an Microsoft.Exchange.Data.Transport.Email.EmailMessage Body isn't that straightforward: some characters like tabulations (\t) can easily be missing.

Initial approach

My original approach was the following:

public static string GetStringBody(this IEmailBody body)

Installing and working with a Transport Agent in an Exchange plugin

While it might seem quite trivial from the Microsoft documentation, installing and working with transport agents (SmtpReceiveAgent, RoutingAgent, and DeliveryAgent) is full of footguns.
Here is a little post-mortem after playing around with an SmtpReceiveAgent with an Exchange Server 2019 (with countless days of debugging and borderline madness) to hopefully get you there in less than a month.

Installation

The gist (no pun intended) of the installation process can be found here, and is quite well documented. Other useful links to understand how agents are structured are this one (or any of its variants depending of which agent you want to create) and [this one](https://learn.microsoft.com/en-us/exc
