chore(dnn): #131 migrate 12 RazorComponent templates to Razor14 (source-level, runtime pending)

[jsboige]

Summary

Source-level migration of the 12 deprecated ToSic.Sxc.Dnn.RazorComponent templates (the Dnn-specific base, removed in 2sxc 21 LTS) to the modern Dnn-agnostic Custom.Hybrid.Razor14 base. This is the last remaining 2sxc breaking-risk identified in the DNN 10.3.2 + 2sxc 21 upgrade arc (#458 / #131).

Note: this is a SOURCE-LEVEL migration only. Runtime validation is PENDING on the sandbox (see §Validation). These .cshtml files are interpreted by 2sxc at runtime in DNN — they are not compiled by dotnet build, so they cannot be validated locally by the .NET pipeline. The PR is opened for sandbox runtime validation, per the ai-01 dispatch (2026-06-25 14:05).

Dispatched by ai-01 (coordinator). Worker: po-2023.

Scope (12 files — all under DNNPlatform/)

News5/bs3 (5):

• _Details.cshtml
• _List.cshtml
• _List archive.cshtml
• _List Columns.cshtml
• _List Columns without images.cshtml

Content/bs3 (7):

• Layout/_Line.cshtml
• Link/_Large emphasized link.cshtml
• Link/_List of document-links.cshtml
• Link/_List of icon-links.cshtml
• Link/_List of image-links with overlay.cshtml
• Link/_List of image-links.cshtml
• Link/_List of links.cshtml

0 files under Cards/ (release freeze respected — master stays bef3bc6c).

API migrations (semantics preserved, 2sxc 21-compatible)

Legacy (RazorComponent)	Modern (Razor14)	Count	Where
@inherits ToSic.Sxc.Dnn.RazorComponent	@inherits Custom.Hybrid.Razor14	12×	all
Request.QueryString["category"]	CmsContext.Page.Parameters["category"]	5×	News5
Dnn.Module.ModuleID	CmsContext.Module.Id	4×	Content/Link
@using ToSic.Eav.Run;	@using ToSic.Sxc.Context;	4×	News5 _List*
CustomizeSearch(... IContainer moduleInfo ...)	CustomizeSearch(... IModule moduleInfo ...)	4×	News5 _List*

The CustomizeSearch signature is aligned with the repo's already-modern News5/DnnSearch/SearchMapper.cs (Custom.Hybrid.Code12, ICustomizeSearch, IModule). Each of the 4 _List* overrides preserves its own logic (_List.cshtml = stream cleanup + per-entity querystring; the 3 others = searchInfos.Clear() to prevent duplicate results) — none were removed or merged into SearchMapper, to avoid changing behavior without runtime tests.

APIs preserved (still valid in Razor14 — confirmed)

App.Data, AsList, AsDynamic, Content, CreateInstance, GetService, Edit.TagToolbar / Edit.Enabled, Text.Has, Tags.* (Tags.Nl2Br, Tags.Strip), @RenderPage, @Html.Partial, @Html.Raw, CmsContext.View.Identifier (already modern in _Line.cshtml).

Out-of-scope shared dependencies left untouched (per dispatch perimeter):

• News5/bs3/shared/_Parts.cshtml — already Custom.Hybrid.Razor12 (2sxc 21 supports Razor12).
• Content/bs3/Link/_LinkHelper.cshtml — helper with no @inherits, not in the 12-template list.

⚠️ Runtime validation PENDING on sandbox

These points cannot be verified by dotnet build (2sxc interprets .cshtml at runtime). To validate on the DNN sandbox post-2sxc-21-upgrade:

1. CustomizeSearch override signature (IModule) in the 4 News5 _List* — confirm Custom.Hybrid.Razor14 still exposes the virtual override. If 2sxc 21 dropped template-level overrides in favor of the ICustomizeSearch interface, fall back to the existing News5/DnnSearch/SearchMapper.cs pattern (move the per-template logic into SearchMapper or a per-view SearchMapper).
2. CmsContext.Page.Parameters["category"] null-behavior — verify it returns null when the parameter is absent (downstream Text.Has(...) handles null). If it throws on missing key, wrap with .ContainsKey("category").
3. _LinkHelper.cshtml:30 uses Dnn.Portal.PortalAlias.HTTPAlias (legacy). NOT migrated here (outside the 12-template scope, no @inherits). It may break when instantiated from a Razor14 template → candidate follow-up PR if the sandbox reveals it.

LGTM — migration source-level complète et cohérente (12 templates, #131).

Vérifications :

• @inherits : 12/12 ToSic.Sxc.Dnn.RazorComponent → Custom.Hybrid.Razor14. Aucun fichier oublié.
• APIs DNN-spécifiques : les 4 occurrences de Dnn.Module.ModuleID → CmsContext.Module.Id (l'équivalent CMS-agnostique de Razor14).
• Le point qui compte sous Razor14 — c'est une base CMS-neutre, donc tout appel Dnn.* restant casserait au runtime. J'ai scanné les 12 fichiers migrés : 0 référence Dnn.* résiduelle (les 4 hits du diff sont tous des lignes - supprimées). Le risque de runtime-breakage prévisible est donc écarté côté source.

Le caveat « runtime pending » du titre est honnête et approprié : la migration source est complète, reste à valider contre une instance DNN/2sxc live. Rien à redire sur ce qui est dans le scope du PR.

Sandbox runtime-readiness assessment (2026-06-25, po-2023)

Per ai-01 dispatch v2 ("runtime-valider #596 → un-gate merge ; fallback explicite = documente précisément le gap, ne stalle pas"). Sandbox not yet booted this tick — but the readiness picture is now precise, and better than expected (the hard piece is present).

✅ Present & functional (verified this tick)

• LocalDB MSSQLLocalDB started; the ArgumentumGames DB is a real, populated DNN 9.11.1 database — 163 base tables, Version row 9.11.1, full aspnet_* membership schema.
• DNNPlatform/bin/: DNN 9.11.1.19 + 2sxc 21.07.00 (ToSic.Sxc.Dnn.dll) — the dispatch's "2sxc 21" target, confirmed. Razor14 is fully supported at this version.
• The 12 migrated templates are present in-tree under Portals/1/2sxc/{News5/bs3, Content/bs3/{Link,Layout}}/.

→ The sandbox is bootable. The web.config reading Data Source=REPLACE is a committed placeholder, not a missing DB.

⚠️ Local-config gaps before first boot (none of these are committable — secrets/DB are out-of-band)

1. Connection string web.config → Data Source=REPLACE placeholder. Set locally to (localdb)\MSSQLLocalDB;Database=ArgumentumGames;Integrated Security=True (matches UPGRADE-ASSESSMENT §1).
2. machineKey → validationKey="REPLACE" decryptionKey="REPLACE". Generate a throwaway dev key locally. Never commit — production machineKey is GDrive-authoritative (UPGRADE-ASSESSMENT §1).
3. IIS Express config: no applicationhost.config in repo. Create one + launch via /config: + explicit site binding (gotcha: /path: is broken — feedback-dnn-iis-express, use /config: + named site).

⚠️ The actual DoD step (where the work is)

4. The 12 templates are file-based Razor, interpreted by 2sxc at runtime. A render-check needs each template assigned to a 2sxc App module on a DNN page (which pages exist in ArgumentumGames is unverified), then browser-navigate + screenshot per template → OK/KO report. Realistic effort ~30-60 min of focused sandbox work.

Bottom line (honest)

• I did not fabricate a validation report this tick — the sandbox is bootable but not yet booted, and runtime validation needs step 4 (page-assignment + browser verify).
• This is materially closer to runnable than "non-functional": the populated DNN 9.11.1 DB (the usually-hard part) is present.
• Concrete next step = execute the 4-step boot recipe + browser verify. I can do this on the next tick if dispatched, or ai-01 can scope it as a focused sandbox-boot task. The merge-un-gate (DoD) remains gated on step 4.

Sandbox boot attempted (2026-06-25, po-2023 tick 2) — precise blocker found: bin/ SDK-assembly contamination

Update to my earlier readiness comment. I moved from "readiness assessment" to an actual boot attempt this tick. The boot infrastructure works, but DNN itself cannot start due to a pre-existing bin/ corruption — independent of the 12 templates and of the #596 migration.

What booted ✅

• LocalDB MSSQLLocalDB + ArgumentumGames DB (DNN 9.11.1, 163 tables) — alive.
• IIS Express site "DNN Argumentum" (:8090, Clr4IntegratedAppPool v4.0, physicalPath DNNPlatform/) — existing Documents/IISExpress/config/applicationhost.config already had it.
• Local web.config edits (LocalDB conn string, throwaway dev machineKey) — applied, reverted after (never committed; machineKey is GDrive-authoritative in prod).
• DNN did handle requests (HTTP responses, not connection refused).

❌ Blocker: cascade of FileLoadException — bin/ has .NET 6/9 SDK contract assemblies

DNN returns HTTP 500, title (FR locale): « Impossible de charger le fichier ou l'assembly '<System.X>' … La définition trouvée du manifeste de l'assembly ne correspond pas à la référence de l'assembly (0x80131040) ». The failing assembly advances with each web.config redirect I patch — a cascade, not a single fix:

Assembly (physical bin/)	AssemblyVersion	FileVersion	Expected by redirect / libs
System.Buffers	4.0.4.0	4.600.24.56208 (.NET 6 SDK)	4.0.3.0 (Imageflow/2sxc)
System.Collections.Immutable	9.0.0.0	9.0.24.52809 (.NET 9 SDK)	~5.0/6.0
System.Text.Json	9.0.0.0	9.0.24.52809 (.NET 9 SDK)	~5.0/6.0
System.Memory	4.0.1.2	4.6.31308.01	4.0.1.1
System.Numerics.Vectors	4.1.4.0	4.6.26515.06	4.1.3.0/4.1.4.0
System.Runtime.CompilerServices.Unsafe	6.0.0.0	6.0.21.52210	4.0.4.1/4.5.x

The fileVersions (4.600.x, 9.0.x) are .NET 6/9 SDK forwarder/contract assemblies — they should not be in a .NET Framework 4.8 DNN bin/. They appear to have been dropped by a global-tool / SDK NuGet restore polluting bin/. System.Collections.Immutable 9.0.0.0 + System.Text.Json 9.0.0.0 are the smoking gun: a DNN 9.11.1 site on .NET Framework 4.8 cannot bind these.

Why I stopped at whack-a-mole

Patching binding redirects one-by-one (I did fix System.Buffers → 4.0.4.0; that advanced the error to System.Collections.Immutable) is a fragile band-aid: ~6+ redirects to update, and the newer contract assemblies may be ABI-incompatible with the Imageflow/2sxc code compiled against the older versions → runtime errors even if binding succeeds. The correct fix is a clean bin/ re-deploy of the correct-framework assemblies (DNN 9.11.1 + 2sxc 21.07 + Imageflow.Net 0.14 built for net48), not redirect-patching.

Conclusion (honest, for the WE review)

• chore(dnn): #131 migrate 12 RazorComponent templates to Razor14 (source-level, runtime pending) #596 runtime validation remains gated — but now on a characterized blocker (bin/ SDK-assembly contamination), not an unknown. The templates themselves were not reached.
• This is a pre-existing sandbox-environment issue, not a defect of the chore(dnn): #131 migrate 12 RazorComponent templates to Razor14 (source-level, runtime pending) #596 migration. The migration (source-level, 12 files) is orthogonal to it.
• Recommended path to un-gate chore(dnn): #131 migrate 12 RazorComponent templates to Razor14 (source-level, runtime pending) #596: (1) clean DNNPlatform/bin/ re-deploy from a known-good DNN 9.11.1 + 2sxc 21.07 install package; (2) re-run this boot recipe (LocalDB ready, IIS Express config ready); (3) then browser-verify the 12 templates. This is an environment/ops task (jsboige or a focused sandbox-repair tick), not a 2-minute config change.
• The boot recipe itself is proven (IIS Express + LocalDB + conn string + dev machineKey all worked) — reusable once bin/ is clean.
