Dzidek.Net.AutoUpgrade.Service 1.0.1

Windows service with auto upgrade feature

An auto-updating Windows service with the ability to send a new compressed version on demand

Packages (Dzidek.Net.AutoUpgrade.Service and Dzidek.Net.AutoUpgrade.Upgrader) allow us to implement a service with an automatic update on demand if part of our application is installed outside our servers where we do not have administrator rights or even log in

How it works

AutoUpgrade has two services (one with the ".Service" suffix and the other with the ".Upgrader" suffix). The "Service" is responsible for downloading and saving new versions in the directory. The directory where new versions are saved is watched by "Upgrader" and if a new file has been created, it stops "Service", copies new files and starts "Service".

You can control it from the outside when an update happens because it happens when you save a new version and you decide when you give a new version

Basic usage

Service

In appSettings.json:

{
  "AutoUpgrade": {
    "ServiceName": "AutoUpgrade"
  }
}

In program.cs:

builder.Host
    .UseAutoUpgradeService(builder.Configuration.GetSection("AutoUpgrade").Get<AutoUpgradeServiceConfiguration>()!);

Below is an example of how to use it through the API over HTTP/HTTPS. You can use it as you want

app.MapGet("/",
    (IAutoUpgradeService autoUpgradeService) => $"Hello World from service '{autoUpgradeService.GetVersion()}'!");
app.MapPost("/", (IFormFile file, IAutoUpgradeService autoUpgradeService) => autoUpgradeService.Upgrade(file));

Configuration

• ServiceName - service name - should be the same in "Service" and "Updater", both add suffixes to distinguish the two services
• NewVersionDirectoryName - name of the directory where new versions will be saved. This directory will be watched by the Upgrader. This directory will be placed in the service directory
  • Default value: NewVersion
• ServiceNameSuffix - service suffix name
  • Default value: Service
  • Example: In the example above, the service name will be "AutoUpgrade.Service"

Upgrader

In appSettings.json:

{
  "AutoUpgrade": {
    "ServiceName": "AutoUpgrade",
    "ServicePath": "[The required path to the directory where the exe file is located]"
  }
}

In program.cs:

builder.Host
    .UseAutoUpgradeUpgrader(builder.Configuration.GetSection("AutoUpgrade").Get<AutoUpgradeUpgraderConfiguration>()!);

Configuration

• ServiceName - service name - should be the same in "Service" and "Updater", both add suffixes to distinguish the two services
• ServicePath - the required path to the directory where the exe file is located
• ServiceNameSuffix - service suffix name
  • Default value: Service
  • Example: In the example above, the service name will be "AutoUpgrade.Service"
• UpgraderNameSuffix - upgrader suffix name
  • Default value: Upgrader
  • Example: In the example above, the service name will be "AutoUpgrade.Upgrader"

Create service in windows

You should call with admin rights. You should first create Service because Upgrader automatically starts Service

sc.exe create "AutoUpgrade.Service" binpath="[PATH]\AutoUpgrade.Service.exe" start=auto
sc.exe create "AutoUpgrade.Upgrader" binpath="[PATH]\AutoUpgrade.Upgrader.exe" start=delayed-auto

Working example

The working example is available in the GitHub repository AutoUpgrade.

For testing purposes, you need to build projects and install windows services. You can then send the new version of the service via HTTP to http://localhost:9000. You can use swagger to do this at http://localhost:9000/swagger
