Visual Studio used to be basically mandatory for developing C# and costs $500 per year per developer or more (unless you are happy violating the license of the community edition). Paying for libraries is also completely normal in the C# ecosystem, it's easy to pay another couple thousand per developer for library licenses.
I think you tend to get good value for your money, developer salaries are expensive after all. But for any other language (maybe besides C/C++) this is much less common and the paid products that do exist are much cheaper.
How does this relate to docker? Only really in combination with the other attributes. Rsyncing files into production isn't as traceable, organized, structured or auditable as many of the Docker-based solutions out there. Those solutions can get expensive at scale, but if you use C# you are used to that
Hence the "used to". Both became options 8 years ago and took a bit to mature. Before 2016 everyone had Visual Studio licenses and on top of that got JetBrain's VS extensions.
