Behavior of Edit.WordDeleteToEnd on single-line C# comment has changed

_This issue has been moved from [a ticket on Developer Community](https://developercommunity.visualstudio.com/t/Behavior-of-EditWordDeleteToEnd-on-sing/10862435)._

\[severity:It bothers me. A fix would be nice\] \[regression\] \[worked-in:16.11.4 for sure, not sure about VS2022\]
Previously, using Edit.WordDeleteToEnd (typically Ctrl+Del) with the cursor at the “//” of a single-line C# comment would delete the comment marks and spaces preceding the first word in the comment. E.g. if invoked on the line (^ indicates cursor position)

`^// This is a comment`

Ctrl+Del would yield

`This is a comment`

In recent versions of Visual Studio 2022 (I don’t remember exactly which version), this behavior has changed and in that situation the command now deletes the entire line. This happens only when the cursor is immediately before the “//” of the comment, if placed elsewhere the behavior is unchanged.

There is an analogous change in the behavior with a multi-line (/\* \*\/) comment, in this case if the cursor is positioned immediately preceding the "\/\/", Edit.WordDeleteToEnd results in the entire comment being deleted.

I have gotten used to using Ctrl-Del to remove comment marks, and whether by design or not, this change is very inconvenient. I have not found another command to achieve the previous behavior. Can the previous behavior either be restored, or can we have an alternative command that implements the previous behavior?

This issue is currently being investigated. Our team will get back to you if either more information is needed, a workaround is available, or the issue is resolved.

Reproduce the behavior in Visual Studio 2022 with Edit.WordDeleteToEnd (typically Ctrl+Del) at the start of single-line and multi-line C# comments. Compare the current deletion with the documented prior behavior, and consider the issue complete when the previous behavior is restored or an alternative command provides it.
