Provides full-flavour implementation of reliable background service with Serilog logging and environment dependent configuration.

Code Example

Hosting SafeBackgroundService (and other IHostServices)

class SafeProgram : SafeProgramBase<HostedServiceLikeSafeBackgroundService>
    protected override void ConfigureServices(HostBuilderContext hostContext, IServiceCollection services)
            .AddSingleton<ISomeService, SomeServiceImpl>();

        // do not add HostedService to services, it has already been added

    public static void Main(string[] args)
        new SafeProgram().run();

Implementing SafeBackgroundService

To use this class you should override at least one of following methods:

    protected abstract Task ConnectAsync(CancellationToken cancellationToken);

    protected abstract Task DisconnectAsync();

    protected abstract Task ExecuteIterationAsync(CancellationToken cancellationToken);

You also need to provide ISafeBackgroundServicePanicHandler to the constructor if you don't use SafeProgramBase. If you do use SafeProgramBase, it will be automatically provided and will stop all services when one of them raised panic event.


When creating long-running background services you have to deal with failures caused by environment like network failure, SQL timeout or other. Most of those conditions are temporary and should not cause service failure.

This implementation separates small failures (wait and try again) and big failures (stop, wait, initialize and try again).


Use NuGet.

API Reference

Look at code example should be enough.


Not included in this release (but be patient, I'll migrate it later)


Every contributor is welcome here. But keep it simple.


I like MIT licence for my work, so this one will be used.
