Configure C# dep injector for a console app or unit test that logs to console via Microsoft.Extensions.Logging and via Serilog

ConfigureSerilogWithMel.cs

        private static ServiceProvider ConfigureServices()
        {
            // Configure console logging for unit-test
            var serviceProvider = new ServiceCollection()
                .AddLogging(builder =>
                {
                    // workaround for double-gating of log-levels by MEL and Serilog
                    builder.SetMinimumLevel(LogLevel.Trace);
                })
                .BuildServiceProvider();
            var loggerFactory = serviceProvider.GetService<ILoggerFactory>();
            Log.Logger = new LoggerConfiguration()
                .WriteTo.Console()  // or instead .ReadFrom.Configuration(configuration)
                // set actual minimum log level here (or instead use config)
                .CreateLogger();
            loggerFactory.AddSerilog();
            return serviceProvider;
        }
