Yes, it does.

Found a couple typos. Thanks for adding these.

Just FYI this will be undone every time we run CI since this information is automatically generated. This issue will need to be fixed: mono/api-doc-tools#356

[Youssef1313]

Is the reason of the missing information known ?

[mairaw]

I don't know @Youssef1313. This would be a question for @joelmartinez.

@Youssef1313 the tool which generates these signatures from compiled assemblies (which @mairaw linked to the relevant repo/issue) needs to be updated. It's on my team's list, we just need to get through a few other high priority tasks before we get there :) Once that issue is resolved, the missing VB.NET signatures will be systematically added (just as Maira mentioned, they will currently be systematically removed by the tool as they are regenerated every time API discovery is run)
