Changelog

[2.1.1] - 2026-08-11

Stable setup/uninstall phase codes, environment and file metadata, complete self-test output, exception chains with HRESULT/stacktrace, and per-step rollback diagnostics.
Installer-log fallback from ProgramData to Temp plus a setup button for opening diagnostic logs.
Post-write verification of shortcuts, uninstall executable and essential uninstall-registry values.
Regression coverage for pre-mutation rollback wording, diagnostic context, log fallback and UI-report isolation.

Pre-mutation failures now explicitly report that no rollback was required; completed rollbacks are only reported as successful when every restoration step succeeded.
Self-test timeout handling is bounded after termination is requested and records kill/capture status.
Technical installer acceptance is explicitly separated from BizTalk WMI/environment validation.
Setup and uninstall preserve undeletable backup/quarantine data and record a successful completion with a cleanup warning.

Transactional Windows setup/updater with SHA-256 payload manifest, isolated staging, pre/post activation self-tests, rollback, shortcuts and uninstall registration.
Certutil-compatible installer ZIP as Base64 TXT plus separate ZIP SHA-256 file.
WMI-free application self-test and regression test project covering persistence, diffs, restore safety, CSV hardening and installer rollback.
UAC manifest and single-instance protection for the management application.

Snapshot and plan JSON writes now replace files atomically and keep BOM-tolerant reads.
Snapshot diffs identify artifacts by application and name.
Restore planning rejects snapshots from a different target server.
Real shutdown/restore requires confirmation of the fully prepared and saved plan.
Runtime logs are written to %ProgramData%\BizTalkPlatformManagementTool\Logs with executable-directory fallback.
WMI query objects and WMI method output objects are disposed deterministically.
CSV exports neutralize formula-like cell prefixes.

Projekt auf BizTalkPlatformManagementTool umbenannt.
Solution, Projektdatei, Namespace, Assemblyname und Standard-Ausgabepfad angepasst.
Dokumentation aktualisiert und Installation.md ergänzt.
