Common.Updater 1.0.4

🔄 Common.Updater

A lightweight ClickOnce-compatible update service designed for Precitec desktop applications. It allows software to check for and install updates from a shared network folder (UNC path) — fully integrated with Dependency Injection and ClickOnce publishing.

✅ Features

✔ Automatically detects newer versions in shared folder
✔ Launches .application or .exe for upgrade
✔ Supports ClickOnce-based publishing and folder-based deployment
✔ Easily integrated with your WPF application startup
✔ Supports graceful restart after update
✔ Safe for use in DI and production-grade apps

📦 Installation

Install via internal NuGet feed:

dotnet add package Common.Updater --version 1.0.x

🚀 Setup in Your Application

1. Register in Startup.cs or App.xaml.cs

services.AddCommonUpdater(
    sharedFolder: @"\\po-s-dat\dsp\Software Produktion\_Tools\",
    appName: "HPWLSBurnInTest"
);

📁 This will target: \po-s-dat\dsp\Software Produktion\_Tools\HPWLSBurnInTest_Update\ClickOnce\Application Files\

2. Auto-Check and Update on Startup (Not supporter at the moment)

Instead of repeating update logic, just call:

await UpdaterHelper.AutoUpdateAndShutdownAsync(_host.Services, Log.Logger.Error);

• If an update is found, it launches and shuts down the app.
• If no update is found, the app starts normally.

3. Manual Use (Optional)

var updateService = serviceProvider.GetRequiredService<IUpdateService>();
var update = await updateService.CheckForUpdatesAsync();

if (update != null)
{
    updateService.RunClickOnceUpdate(update);
    await updateService.RestartSoftware();
}

🧩 Publish Folder Structure

For each published version of the software, use:

\po-s-dat\dsp\Software Produktion\_Tools\
    HPWLSBurnInTest_Update\
        ClickOnce\
            Application Files\
                HPWLSBurnInTest_1_0_7\
                    HPWLSBurnInTest.application

✅ Enable “Make available offline” on the folder
✅ Make sure Publish Version increments with every publish
✅ UNC path must remain stable
