EndogenousUpdater 6.0.0.1

Introduction

Performs application updates using the application itself as the updater.

Getting Started

To add EndogenousUpdater to your project, simply register it in your service collection:

services.AddEndogenousUpdater(services, u =>
{
    u.WithVersionBasedUpdates(v =>
    {
        v.Source.WithDirectoryVersion(updateDirectoryPath);
        v.Destination.WithAssemblyVersion(Assembly.GetEntryAssembly());
    });
    u.ZipDirectorySource(updateDirectoryPath); 
    u.CurrentDirectoryDestination();
    u.WithRelaunchOptions(o => o.InferLaunchOptions());
});

This will get you endogenous updater, using version based update checks with the provided update updateDirectoryPath. The client will compare its entry assembly version to the verison number of the most recent zip file in the format XXXX-1.2.3.4.zip.

Note, if you want to keep things simple, try this instead:

services.AddEndogenousUpdater(@"\\my\lan\update-source");

Then somewhere in your code, request an instance of IEndogenousUpdater and call ApplyUpdatesAsync.

public class MyUpdater
{
    private readonly IEndogenousUpdater updater;

    public MyMigrator(IEndogenousUpdater updater)
    {
        this.updater = updater;
    }

    public async Task ApplyUpdatesAsync(CancellationToken cancellationToken)
    {
        await updater.ApplyUpdatesAsync(cancellationToken);
    }
}

If you have logging enabled, you should see something like this in your logs:

Why EndogenousUpdater

• Simple as you want to make it. No 3rd party installers, no restrictions on how you package and deploy your application.
• Full async/await support.
• Fully customizable. Dependency Injection based means you can overwrite any aspect of the project.
• Familiar code structure. Based on the Microsoft.Extensions.* projects. If you are already leveraging those packages in your project, this package will seem very familiar in it's setup.
