I've found an simple trick for azure app ,see https://github.com/aspnet/Logging/tree/dev/src/Microsoft.Extensions.Logging.AzureAppServices, please add the package "Microsoft.Extensions.Logging.AzureAppServices": "1.0.0-preview1-final" and update related dependencies, add the azure diagnostics in startup.cs like this :

loggerFactory.AddConsole(Configuration.GetSection("Logging"));
loggerFactory.AddDebug();
loggerFactory.AddAzureWebAppDiagnostics(); // for default setting.

or for custom setting:

loggerFactory.AddAzureWebAppDiagnostics(new AzureAppServicesDiagnosticsSettings( ...)); // add custom setting.
// see here for detailed member properties: https://github.com/aspnet/Logging/blob/dev/src/Microsoft.Extensions.Logging.AzureAppServices/AzureAppServicesDiagnosticsSettings.cs

And enable the diagnostics log on azure, both logging on blob and file are work well. No need for any extra configuration. :)
