- Add support for ':line 123' format in addition to ':123:45' format - Only set selection when line number is greater than 0 - Ensure column defaults to 1 when not specified Fixes file navigation in debug console for C# stack traces. Stack traces like 'Program.cs:line 6' now correctly navigate to line 6 instead of line 1.

Pull request overview
This PR adds support for C# stack trace format (:line 123) in the debug console link detector, enabling proper navigation to specific line numbers when clicking on C# stack traces. The implementation maintains backward compatibility with existing formats (:123, :123:45) while also fixing a pre-existing bug where column numbers would evaluate to NaN when not specified.
Key Changes
- Extended regex patterns to recognize both
:line 123and traditional:123:45formats - Fixed column number handling to default to 1 instead of
NaNwhen column is not specified - Added validation to only set editor selection when line number is greater than 0

Missing test coverage for the new :line 123 format. The existing tests only cover the :123:45 format. Consider adding tests for:
file.cs:line 6(C# stack trace format)file.cs:line 6:10(C# format with column)- Mixed scenarios to ensure backward compatibility
- Add test for ':line 6' format - Add test for ':line 6:10' format with column - Add test for mixed stack trace formats - All tests passing (19/19)

Hm, looks like these tests fail on Windows: |
The test was failing on Windows because the regex only matched Unix-style forward slashes (/). Added platform-specific regex patterns to handle both Windows backslashes (\) and Unix forward slashes (/). Fixes the failing Windows tests in PR microsoft#281536.

Problem
When clicking on C# stack trace links in the Debug Console (e.g.,
Program.cs:line 6), VSCode only opens the file at line 1 instead of navigating to the specific line number.Root Cause
The link detector's regex pattern didn't support the
:line 123format commonly used in C# stack traces.Solution
LINE_COLUMNregex to support both:line 123and:123:45formatscreatePathLinkto only set selection when line number > 0Testing
