Log in the application

Innova Framework uses Microsoft.Extensions.Logging for logging.

This allows the use of various 3rd party logging providers to perform the actual logging (to text files, database, web service, etc.). See examples of providers here.

When there is a need to log, inject ILogger in the constructor.

Requirement: When the button in CategoriesShowDialogMenu is clicked, it should be logged.

Task: Inject ILogger and call LogInformation in onExecute.

Execution:

    public class CategoriesShowDialogMenu:MenuModelEntity<Northwind.Data.Entity.CategoriesShow>
    {
        private readonly IWindowDialogService _windowDialogService;
        private readonly ILogger<CategoriesShowDialogMenu> _logger;

        public CategoriesShowDialogMenu(IEventAggregator eventAggregator,
                                        IWindowDialogService windowDialogService,
                                        ILogger<CategoriesShowDialogMenu> logger) :base(eventAggregator)
        {
            _windowDialogService = windowDialogService;
            _logger = logger;

            Header = "Show dialog";
            Description = "Click to show dialog";
            GroupName = MenuGroupNames.Functions; 
            SetImages(Innova.Prism.Library.Styles.WindowsMenuImages.gear);
            Command = new LogDelegateCommand(ExecuteCategoriesShowDialogMenu, CanExecuteCategoriesShowDialogMenu);

        }

        private bool CanExecuteCategoriesShowDialogMenu()
        {
            return this.Entity != null;
        }

        private void ExecuteCategoriesShowDialogMenu()
        {
            _logger.LogInformation("Button clicked");
            _windowDialogService.ShowInformation($"{this.Entity.CategoryName} - dialog is clicked.");

        }
    }

When the button is clicked, it is logged:
