Prism.Logging.Serilog

Give a Star! :star:

If you like or are using this project please give it a star. Thanks!

Getting started :rocket:

To use the Prism.Logging.Serilog, first install the NuGet package:

Install-Package Prism.Logging.Serilog

Then register Serilog with Prism's IContainerRegistry using RegisterSerilog():

protected override void RegisterTypes(IContainerRegistry containerRegistry)
{
    // ...

    containerRegistry.RegisterSerilog();
}

Log events from Prism will be written to Serilog's Log.Logger by default. Alternatively, you can provide a specific instance of a Serilog.ILogger:

private Serilog.ILogger _logger = Log.Logger;

protected override void RegisterTypes(IContainerRegistry containerRegistry)
{
    // ...

    containerRegistry.RegisterSerilog(_logger);
}

Mapping of Prism Log messages to Serilog

Prism.Logging.Serilog does The Right Thing™ :), as you'd expect:

• The Priority set in log messages written via Prism gets forwarded to Serilog as a context property called Priority, with the value of the priority as a string. e.g. "High".

• Log messages forwarded to Serilog have the SourceContext property set to Prism.Logging.Serilog.SerilogLoggerFacade, allowing developers to use use filters, sub-loggers, and minimum level overrides.

Example

In the source code you can find a demo project of a WPF application using Prism and Serilog. The initial setup looks something like this:

public partial class App
{
    protected override void OnStartup(StartupEventArgs e)
    {
        // Configure Serilog and the sinks at the startup of the app
        Log.Logger = new LoggerConfiguration()
            .MinimumLevel.Debug()
            .WriteTo.File(path: "MyApp.log")
            .CreateLogger();

        base.OnStartup(e);
    }

    protected override void OnExit(ExitEventArgs e)
    {
        // Flush all Serilog sinks before the app closes
        Log.CloseAndFlush();

        base.OnExit(e);
    }

    protected override void RegisterTypes(IContainerRegistry containerRegistry)
    {
        // Register your ViewModels, Services, etc...
        // ...

        // Register Serilog with Prism
        containerRegistry.RegisterSerilog();
    }

    protected override Window CreateShell()
    {
        return Container.Resolve<MainWindow>();
    }
}
