[VS Integration]The “Uncomment Selected Lines” button in the toolbar does not work for single-line comments.

[vfp9]

To Reproduce Steps to reproduce the behavior:

1. Select a line of code and click the “Comment Selected Line” button on the toolbar.
2. Selecting the code that has just been commented and clicking the “Uncomment Selected Lines” button will not uncomment it.

Which version of X#? And which version of Visual Studio? Over here it works with VS 17.11.5 and X# 2,21.0.3, which will be released soon. It even works when the cursor is on the line and nothing is selected. I am using the menu options "Comment Selection" and "Uncomment Selection"

Visual Studio(Ver 17.11.5) and X# (Ver 2.21.0.3)

By “Select a line of code”, I mean, select a line of code(Just like selecting multiple lines of code), not “cursor is on the line and nothing is selected”.

Can you record a video to show what you're doing?

If I understood correctly:

1. type in an empty line:

sometext

2. Select the whole word and choose comment, this puts block comments around the word

/*sometext*/

3. Select again the full line, including the / / markers and choose uncomment, nothing happens, I assume because the caret is at the very end or very beginning of the line

4. In order for the text to be actually uncommented, the caret needs to be put inside the block comment and then choose uncomment

cpyrgas, Your understanding is correct.！

Ok, but what do you expect to happen for a line of code like this, where the cursor is positioned at the start of the line

   x := Left( /*comment1*/ somevar, /*comment2*/ 10)

Should both comments be uncommented?

The idea behind the current behavior is:

• if the line starts with // or && then the whole line is uncommented regardless of where the cursor is located, as long as the cursor is on that line
• if the line contains a /* ... */ then the block where the cursor is located is uncommented

This is also what the C# language service does for uncommenting.

Robert，I see no problem with handling it that way.
