UseSerilog support for .net 7 CreateApplicationBuilder and HostApplicationBuilder

[kris-g]

Are there any plans to implement another UseSerilog extension method for the new application bootstrapper method from .net 7?

an interesting aspect is the global namespace program.cs file. i'd like if we could just builder.Logger.UseSerilog and then add configuration from there, all within builder.Logger. No more redefining Log constant at top except for logging before builder.build() and no need for Host. In most cases I'd guess it'd be just changing from 'Host' to 'Logging' in user code, but I think there is more going on in the backend?

it's also unclear if/when a new console app will come out to match the new webapplication. this may be something to plan for as well.

also i think it's .net6 and up support this

At the same time, I hope to consider the part of MAUI, which comes from: Microsoft.Maui.Hosting.MauiAppBuilder.

thx.

At present, I have finished my work in this way. Code:

public static class MauiProgram
{
    public static MauiApp CreateMauiApp()
    {
        var builder = MauiApp.CreateBuilder();
        builder
            .UseSerilog(loggerConfiguration =>
            {
                var newLoggerConfiguration = loggerConfiguration.WriteTo.Console();
                return newLoggerConfiguration;
            })
...
        return builder.Build();
    }
}

public static class MauiAppBuilderExtensions
{

    public static MauiAppBuilder UseSerilog(this MauiAppBuilder builder, Func<LoggerConfiguration, LoggerConfiguration> options)
    {
        var config = options(new LoggerConfiguration());
        Log.Logger = config.CreateLogger();
        return builder;
    }

}

I think this went into Serilog.Extensions.Hosting last week: serilog/serilog-extensions-hosting#70 - should now be on NuGet in the lastest -dev version of that package.

Please let me know if it's not a match. Thanks!

Can we revisit this issue? It's not been fully addressed.

We are expecting to see an extension method on the HostApplicationBuilder class, which comes from Host.CreateApplicationBuilder() but right now it's only available on HostBuilder.

Reference: SerilogHostBuilderExtensions.cs.

@nblumhardt Any plans to add the above discussed extension method?

[nblumhardt]

@silkfire I think builder.Services.AddSerilog(...) should cover every current application/builder model; does that one not work in your scenario?

[silkfire]

Sure, as long as it's made clear in the documentation that UseSerilog cannot be used anymore with this scenario. Otherwise it's confusing why there's no equivalent for it when using minimal APIs.

👍 raised serilog/serilog-aspnetcore#368 - thanks!
