Pull request overview
Fixes how integration tests resolve and pass the AttachVS executable path so VS can auto-attach when debugging vstest.console from data-driven integration tests.
Changes:
- Add a project reference to
AttachVSfrom the TestUtilities project so the executable can be built/copied alongside tests. - Set
VSTEST_DEBUG_ATTACHVS_PATHinIntegrationTestBasewhen debug settings are enabled, pointing toAttachVS.exein the calling assembly’s output directory.

Description
You can specify
DebugVSTestConsole = trueand similar values to data source attributes to debug tests in integration tests, avoiding manually juggling the projects etc.This fixes how we resolve attach vs to automatically attach back to VS.
