Shared common library*

Key aspects

• .NET Core class library for common configuration
• Multiple ASP.NET Core Web Apps to consume common class library

Setup

1. Create a class library and implmement an extension method for IHostBuilder (reference).

   public static IHostBuilder UseCustomLogging(this IHostBuilder builder) => 
       builder.UseSerilog((hostingContext, services, loggerConfiguration) => loggerConfiguration
           .Enrich.FromLogContext()
           .WriteTo.ApplicationInsights(new TelemetryClient(new TelemetryConfiguration("<ikey>")), new TraceTelemetryConverter())
           .WriteTo.File(new CompactJsonFormatter(), "logs\\myapp.json", rollingInterval: RollingInterval.Day)
           .WriteTo.Console());

2. Reference the above library from other .NET projects.

   dotnet add reference <path-to-project>

3. Configure web host to UseCustomLogging (reference):

   public static IHostBuilder CreateHostBuilder(string[] args) =>
       Host.CreateDefaultBuilder(args)
           .ConfigureWebHostDefaults(webBuilder =>
           {
               webBuilder.UseStartup<Startup>();
           })
           .UseCustomLogging();

4. Run the application:

   dotnet run
