I was looking to see if Microsoft was hiring any marketing managers for Microsoft flight (I dream of a 6 figure job in aviation - imagine that) when I came across not what I was looking for but did find this posting: https://careers.microsoft.com/JobDetails.aspx?ss=&pg=1&so=&rw=1&jid=29189&jlang=

I saw a few posts wondering if 3rd party / payware / or freeware support would exist in Microsoft flight. Obviously, like many MS applications, it is a focus as they are hiring dedicated people to make sure it is done right. I’m curious who the select 3rd parties are that get to work with the team during development.
