Release v0.0.0.5

- Scan all stores recursively instead of only the default folder
- Properly release COM objects to avoid leaks
- Better error handling with debug output per store/folder
- Show error message if Outlook is not reachable
- Fallback to default contacts folder if recursive scan finds nothing

 ## Entwicklung
 
+### Voraussetzungen (Build)
+
+- .NET 8 SDK (laeuft auf Windows, Linux und macOS)
+- Fuer den Installer: Inno Setup 6 (Windows) oder Docker (Linux)
+
+### .NET SDK installieren
+
+**Windows:**
+```
+winget install Microsoft.DotNet.SDK.8
+```
+
+**Debian/Ubuntu:**
+```bash
+# Ueber das offizielle Install-Script:
+wget https://dot.net/v1/dotnet-install.sh -O dotnet-install.sh
+chmod +x dotnet-install.sh
+./dotnet-install.sh --channel 8.0
+export PATH="$HOME/.dotnet:$PATH"
+```
+
 ### Bauen
 
+Das Projekt kann sowohl unter Windows als auch unter Linux gebaut werden.
+Die fertige EXE laeuft nur auf Windows (WinForms + COM Interop).
+
 ```bash
-# In Visual Studio oeffnen und bauen, oder:
+# Release-Build
 dotnet build src/StarfaceOutlookSync/StarfaceOutlookSync.csproj -c Release
+
+# Oder publish (mit allen Abhaengigkeiten):
+dotnet publish src/StarfaceOutlookSync/StarfaceOutlookSync.csproj -c Release
 ```
 
+Build-Ausgabe: `src/StarfaceOutlookSync/bin/Release/net8.0-windows/win-x64/`
+
 ### Installer erstellen
 
+Die Setup-EXE wird mit Inno Setup 6 erstellt.
+
+**Linux (Docker - empfohlen):**
+
+Einfachster Weg unter Linux. Baut und packt alles in einem Schritt:
+
+```bash
+# 1. Release bauen
+dotnet build src/StarfaceOutlookSync/StarfaceOutlookSync.csproj -c Release
+
+# 2. Installer erstellen
+docker run --rm -v "$PWD:/work" amake/innosetup installer/setup.iss
+```
+
+Die fertige Setup-EXE liegt danach in `dist/`.
+
+Komplett als Einzeiler (Build + Installer):
+```bash
+dotnet build src/StarfaceOutlookSync/StarfaceOutlookSync.csproj -c Release && docker run --rm -v "$PWD:/work" amake/innosetup installer/setup.iss
+```
+
+**Windows:**
+
 1. [Inno Setup 6](https://jrsoftware.org/isinfo.php) installieren
-2. Release-Build erstellen
-3. `installer/setup.iss` in Inno Setup oeffnen und kompilieren
-4. Setup-EXE wird in `dist/` erstellt
+2. `installer/setup.iss` oeffnen und kompilieren
+3. Setup-EXE wird in `dist/` erstellt
+
+Oder per Kommandozeile:
+```cmd
+"C:\Program Files (x86)\Inno Setup 6\ISCC.exe" installer\setup.iss
+```
+
+**Linux (Wine - Alternative falls kein Docker vorhanden):**
+```bash
+# Einmalig: Inno Setup in Wine installieren
+sudo apt install wine
+wine ~/Downloads/innosetup-6.x.exe
+
+# Kompilieren
+wine "$HOME/.wine/drive_c/Program Files (x86)/Inno Setup 6/ISCC.exe" installer/setup.iss
+```
+
+### Release erstellen
+
+Das Release-Script automatisiert den kompletten Release-Prozess:
+Versionsnummer aktualisieren, bauen, Installer erstellen, Git Tag + Push
+und Gitea Release mit Setup-EXE als Download hochladen.
+
+```bash
+./release.sh <version> ["beschreibung"]
+```
+
+Beispiele:
+```bash
+# Release mit Standard-Beschreibung
+./release.sh 0.1.0.0
+
+# Release mit eigener Beschreibung
+./release.sh 0.2.0.0 "Neues Feature: Auto-Sync"
+```
+
+Das Script fragt beim Start nach Gitea-Benutzername und Kennwort
+und fuehrt dann folgende Schritte automatisch aus:
+
+1. Prueft Voraussetzungen (dotnet, docker, curl, sauberes git)
+2. Aktualisiert Versionsnummer in `.csproj`, `AboutForm.cs` und `setup.iss`
+3. Baut das Projekt (`dotnet build -c Release`)
+4. Erstellt den Installer via Docker (`amake/innosetup`)
+5. Git Commit + Tag (`vX.X.X.X`)
+6. Push zu Gitea (main + tag)
+7. Erstellt Gitea Release mit Setup-EXE als Download-Anhang
+
+Voraussetzungen:
+- .NET 8 SDK
+- Docker
+- curl
+- Gitea-Account mit Push-Rechten auf das Repository
