Pull Request Overview
This PR fixes a bug in the DAC (Data Access Component) implementation where ClrDataAccess::StartEnumMethodInstancesByAddress was incorrectly returning S_OK instead of S_FALSE when failing to get a method descriptor. The fix ensures consistent error handling behavior across both the native DAC implementation and the managed cDAC implementation.
Key changes:
- Fixed the native DAC implementation to return
S_FALSEwhenGetCodeMethodDescfails - Cleaned up redundant code in the managed cDAC implementation by consolidating initialization
