I upgraded my project to .NET Core 2.2.x and got an obsolete warning regarding the following code - both lines:
public void Configure(IApplicationBuilder app,
IHostingEnvironment env,
ILoggerFactory loggerFactory)
{
loggerFactory.AddConsole(Configuration.GetSection("Logging"));
The suggestion to fix is The recommended alternative is AddConsole(this ILoggingBuilder builder)
. I thought that is what I am using.
What am I missing here?
I had the same issue today.
Remove your logging configuration from Startup.cs and go to your Program.cs file and add something like:
var host = new WebHostBuilder()
.UseKestrel()
.UseContentRoot(Directory.GetCurrentDirectory())
.UseIISIntegration()
.UseStartup<Startup>()
.ConfigureLogging((hostingContext, logging) =>
{
logging.AddConfiguration(hostingContext.Configuration.GetSection("Logging"));
logging.AddConsole();
logging.AddDebug();
})
.Build();
This used the 'builder' because the variable 'logging' is an IloggingBuilder (whereas your code is still using ILoggerFactory)
UPDATE: The other method I just tried is to stay inside Startup.cs but move the logging stuff from the 'Configure' method to 'ConfigureServices' like this:
public void ConfigureServices(IServiceCollection services)
{
services.AddLogging(loggingBuilder =>
{
loggingBuilder.AddConfiguration(Configuration.GetSection("Logging"));
loggingBuilder.AddConsole();
loggingBuilder.AddDebug();
});
}
Perhaps keeps the Program.cs less polluted...
