There is no autodetection for code highlighting AFAIK, so you have to specify the syntax in the code blocks.

See these two examples on my system which show proper syntax highlighting for c# when used with the c# hint for the code block:

In order to force c# syntax highlighting you need to start the codeblock like this:

OK this is a known problem, I can reproduce it on 7.8.2 and found the following line in the 7.9 release notes:
https://docs.mattermost.com/install/self-managed-changelog.html#release-v7-9-feature-release

  • Fixed an issue where C# syntax highlighting was not working.

Please update to the latest version which will fix this problem.
