Scope

Project and portal lifecycle — full C# Openness implementation.

When the roadmap routes here, the entire solution is C#. Do not mix with Python wrapper calls. Always load tia-csharp-common first (done by roadmap).

Reference files

Load ONLY the reference file(s) relevant to the task. Do not load all files at once.

| Reference file | When to use | |---|---| | references/project-lifecycle.md | Load when the task involves project-level lifecycle operations: Open, OpenWithUpgrade, Create, Save, SaveAs, Close, Archive, Retrieve, RetrieveWithUpgrade, delete, or copy. | | references/project-attributes.md | Load when the task involves reading project metadata (Author, Name, Version, Path, Size, dates), project history entries, used products, simulation/virtual PLC properties, or accessing the VCI service entry point. | | references/language-settings.md | Load when the task involves project languages, active/editing/reference languages, multilingual text (MultilingualText, MultilingualTextItem), CommentML on devices, or VCI language import options. | | references/umac-and-auth.md | Load when the task involves UMAC-protected project operations, UmacDelegate, Authentication events, ProjectOpenMode (Primary/Secondary), or UMAC user types. | | references/compile.md | Load when the task involves compiling any object (PlcSoftware, HmiTarget, Device, CodeBlock, etc.) via ICompilable or reading CompilerResult. | | references/portal-settings.md | Load when the task involves TiaPortalSettingsFolder (UI language, search index), ObjectIdentifierProvider, SystemDiagnostics settings export/import, or read-only project access. | | references/vci-management.md | Load when the task involves managing VCI workspaces, workspace groups, creating user groups, or connecting/exporting objects to a VCI workspace. | | references/vci-operations.md | Load when the task involves VCI mapped objects, synchronizing changes between project and workspace, or performing object comparisons. |

For tasks spanning multiple areas, load all relevant reference files before generating code.

Execution pattern

1. Create or attach to TiaPortal instance (see tia-csharp-common)
2. Open, create, or retrieve Project
3. Use ExclusiveAccess / Transaction where needed (see tia-csharp-common)
4. Perform project-level Openness operations
5. Save / archive / close at the correct synchronisation point
6. Dispose the TIA Portal session
