how to configure serilog and applicationinsights in App.config?

Question

I was trying to do this to configure serilog to write to application insights. it is in app.config file. But it doesn't work. Is there any alternative approach

<add key="serilog:minimum-level" value="Error"/>
<add key="serilog:using:ApplicationInsights" value="Serilog.Sinks.ApplicationInsights" />
<add key="serilog:write-to:ApplicationInsights" value="fxxx104-dd93-xxxx-8601-xxxxxxxxxxx"/>

Your question is missing some detail. You haven't shown the code where you initialize the logger. Please provide a [mcve]. Also [check the documentation](https://github.com/serilog/serilog/wiki/Debugging-and-Diagnostics#selflog) for how to enable the self-log capability and update your question with the findings. — mason, Apr 27 '21 at 22:35

You should add UseSerilog in Program.cs. You use App.config just want the read keys by code, something like ConfigurationManager.AppSettings["key"].

public static IHostBuilder CreateHostBuilder(string[] args) =>
    Host.CreateDefaultBuilder(args)
        .ConfigureWebHostDefaults(webBuilder =>
        {
            webBuilder.UseStartup<Startup>();
        })
       .UseSerilog((hostingContext, loggerConfiguration) => loggerConfiguration
           .ReadFrom.Configuration(hostingContext.Configuration)
           .WriteTo.ApplicationInsights(new TelemetryConfiguration{ InstrumentationKey = "xxxxxxxxx" },TelemetryConverter.Traces)
        );

Then you can use Log.Information("log details") in yourController.cs to record logs.
