? Features
MVVM Pattern Support
ObservableObject: Base class implementing INotifyPropertyChanged with helper methods
BaseViewModel: Feature-rich view model base class with common UI properties
Base class for implementing property change notifications:
using DotNetTools.Wpfkit.MvvM;
public class MyModel : ObservableObject
{
private string _name;
public string Name
{
get => _name;
set => SetProperty(ref _name, value);
}
private int _age;
public int Age
{
get => _age;
set => SetProperty(ref _age, value, onChanged: () => {
// Execute when age changes
OnPropertyChanged(nameof(IsAdult));
});
}
public bool IsAdult => Age >= 18;
}
BaseViewModel
Rich view model base class with common UI properties:
using DotNetTools.Wpfkit.MvvM;
public class MainViewModel : BaseViewModel
{
public MainViewModel()
{
Title = "My Application";
Subtitle = "Welcome Screen";
Icon = "icon.png";
}
public async Task LoadDataAsync()
{
IsBusy = true;
try
{
// Load data
}
finally
{
IsBusy = false;
}
}
}
Available Properties:
Title: Main title text
Subtitle: Secondary descriptive text
Icon: Icon path or resource
IsBusy: Indicates loading state
IsNotBusy: Inverse of IsBusy
CanLoadMore: Pagination support
Header: Header content
Footer: Footer content
ObservableRangeCollection
Enhanced collection with bulk operations:
using DotNetTools.Wpfkit.MvvM;
var collection = new ObservableRangeCollection<string>();
// Add multiple items efficiently
var items = new[] { "Item1", "Item2", "Item3" };
collection.AddRange(items);
// Replace entire collection
collection.ReplaceRange(newItems);
// Remove multiple items
collection.RemoveRange(itemsToRemove);
// Replace with single item
collection.Replace(singleItem);
AddRange Notification Modes:
NotifyCollectionChangedAction.Add: Notify for each added item (default)
NotifyCollectionChangedAction.Reset: Single reset notification
Logging
Setting Up the Logger
using DotNetTools.Wpfkit.Logging.Extensions;
using Serilog;
public class MyService
{
// Get logger for current class
private static readonly ILogger Log = LogManager.GetCurrentClassLogger();
public void DoWork()
{
Log.Me().Information("Starting work at line {LineNumber}");
try
{
// Your code here
Log.Me().Debug("Processing item");
}
catch (Exception ex)
{
Log.Me().Error(ex, "Failed to process item");
}
}
}
LogManager Features:
GetCurrentClassLogger(): Automatically creates logger with calling class context
Me() extension: Adds line number information to log entries
Serilog Configuration Example
using Serilog;
using DotNetTools.Wpfkit.Logging.Enrichers;
Log.Logger = new LoggerConfiguration()
.MinimumLevel.Debug()
.Enrich.With<UserNameEnricher>()
.WriteTo.Console()
.WriteTo.File("logs/app.log", rollingInterval: RollingInterval.Day)
.CreateLogger();
Configuration Management
Updating Connection Strings
using DotNetTools.Wpfkit.Database;
// Update connection string in appsettings.json
string connectionString = "Data Source=myserver;Initial Catalog=mydb;";
AppSettingsUpdater.UpdateConnectionString(connectionString);
Features:
Automatically locates appsettings.json in application directory
