The legacy VSTO csproj defaults to C# 7.3, but the host code (e.g.
AddInHost, MailItemExtractor) uses nullable reference types — which
require C# 8.0+. Building fails with ~12x
"Feature 'nullable reference types' is not available in C# 7.3".
Sync with the SDK-style Core/UI/Tests projects that already declare
LangVersion=latest + Nullable=enable.

OutlookAddin host project:
- ExplorerRibbon (IRibbonExtensibility + ExplorerRibbon.xml embedded): adds
"תייק ל-EspoCRM" button to Mail Home tab, enabled only when 1+ MailItems
selected; invalidates on Explorer.SelectionChange
- MailItemExtractor: STA-side conversion of Outlook.MailItem to MailEnvelope
primitives (subject, from, to/cc/bcc, body, PR_INTERNET_MESSAGE_ID,
attachments base64), with COM RCW release on each iteration
- RetryQueueProcessor: 30s background drain, max 3 attempts per item,
401 short-circuits the loop, items abandoned (not deleted) after max
- AddInHost: composition root — Logger, SettingsManager, DpapiCredentialStore,
EspoCrmClient, FilingService, RetryQueueProcessor. LaunchFileToCaseAsync
reads selection, extracts, opens dialog, files, stamps "Filed: {name}"
category on success, promotes target into Settings.RecentEntities (max 10),
shows summary MessageBox.
- ThisAddIn: instantiate AddInHost in Startup; CreateRibbonExtensibilityObject
returns ExplorerRibbon
VSTO targets are missing on this machine — host project not built locally.
Core/UI/Tests still green (38 tests passing).

The hand-written legacy csproj at src/OutlookAddin/ is marked Unsupported
by VS 2022. Per PROJECT-BRIEFING.md (steps 5-11), the host project must
be regenerated from the VSTO template inside Visual Studio with the
Office workload — there is no CLI/dotnet template equivalent.
Removing now so the next VS session starts from a clean slate.

Self-contained briefing for a fresh Claude Code session picking up work
on this project from a Windows machine running VS 2022. Covers:
- TL;DR + 4 features
- MailRouter API contract + EspoCRM endpoints
- Tech stack (locked decisions)
- Repo layout + current state
- Step-by-step recipe to regenerate the VSTO host project from the
template (the hand-written csproj is incompatible with VS)
- Conventions + deferred work + open risks
Read this before doing anything: docs/PROJECT-BRIEFING.md.

Initial repo scaffold for a Windows VSTO/COM Outlook Add-in (C#/.NET FW 4.8)
that integrates Outlook desktop with EspoCRM via the existing MailRouter
v1.2.0 endpoint (POST /api/v1/MailRouter/file).
Includes:
- Solution + 4 csproj projects (host, Core, UI, Tests) under src/
- VSTO host project stub (ThisAddIn.cs, requires VS 2022 + Office workload to fully resolve)
- Core/UI/Tests as SDK-style net48 projects (NuGet: Polly, System.Text.Json,
Serilog, CommunityToolkit.Mvvm, xUnit, Moq, FluentAssertions)
- .gitea/workflows/build.yml for Windows runner CI (publish/sign placeholders)
- docs/ARCHITECTURE.md (component diagram, threading model, per-feature flow)
- docs/ONBOARDING.md (Hebrew lawyer-facing install guide)
Server-side already in place: MailRouter v1.2.0 — see plan
~/.claude/plans/resilient-sauteeing-feather.md for the 6-week implementation
plan.
