.NET runs on Linux and has for years, but hosting for it stayed concentrated with the providers that served the Windows era plus the large clouds. The set of hosts documenting it is smaller than the set that could technically run it, which is why the field records what is documented rather than what is possible. Where .NET is listed, deployment is usually a published build or a container image.
17 providers run .NET, listed alphabetically. Mostly Platform as a Service, shared hosting and Containers as a Service, of 13 categories in all. 45 records do not record this field, and cannot appear here either way.

Who is the best .NET hosting provider?
We don't know. A static portfolio and a busy shop need different things from a host, and so do a freelancer and an agency with forty client sites. Nobody pays to be listed here and the order is alphabetical. The guide covers what to compare.
