I-Synergy.Framework.UI 2026.10610.10831

I-Synergy Framework UI

Core UI abstractions and shared components for building cross-platform .NET 10.0 user interfaces. This package provides the foundational layer for all I-Synergy UI implementations including WPF, WinUI, UWP, MAUI, and Blazor.

Features

• Platform-agnostic abstractions for UI services and providers
• Theme management with dynamic accent color support
• Authentication provider for UI security integration
• Token storage service for secure credential management
• ViewModels for common UI scenarios (Language, Theme selection)
• Localization support with built-in resource management
• Extension methods for common UI operations
• Splash screen support with configurable options
• Integration with MVVM framework for ViewModels and services

Installation

Install the package via NuGet:

dotnet add package I-Synergy.Framework.UI

For platform-specific implementations, install the appropriate package:

• WPF: I-Synergy.Framework.UI.WPF
• WinUI: I-Synergy.Framework.UI.WinUI
• UWP: I-Synergy.Framework.UI.UWP
• MAUI: I-Synergy.Framework.UI.Maui
• Blazor: I-Synergy.Framework.UI.Blazor

Quick Start

1. Authentication Provider

The authentication provider enables role-based UI element visibility and command execution control:

using ISynergy.Framework.UI.Abstractions.Providers;
using System.Windows.Input;

public class CustomAuthenticationProvider : IAuthenticationProvider
{
    private readonly IAuthenticationService _authService;

    public CustomAuthenticationProvider(IAuthenticationService authService)
    {
        _authService = authService;
    }

    public bool CanCommandBeExecuted(ICommand command, object commandParameter)
    {
        // Implement custom command authorization logic
        var requiredRole = GetRequiredRoleFromCommand(command);
        return _authService.CurrentUser.HasRole(requiredRole);
    }

    public bool HasAccessToUIElement(object element, object tag, string authorizationTag)
    {
        // Implement custom UI element visibility logic
        if (string.IsNullOrEmpty(authorizationTag))
            return true;

        return _authService.CurrentUser.HasPermission(authorizationTag);
    }
}

// Register in DI
services.AddScoped<IAuthenticationProvider, CustomAuthenticationProvider>();

2. Theme Management

Use the ThemeViewModel to provide theme and color selection:

using ISynergy.Framework.Core.Abstractions.Services;
using ISynergy.Framework.Core.Models;
using ISynergy.Framework.UI.ViewModels;
using Microsoft.Extensions.Logging;

public class ThemeWindow : Window
{
    public ThemeWindow()
    {
        InitializeComponent();
    }
}

// In your application
public class SettingsViewModel : ViewModel
{
    private readonly IDialogService _dialogService;

    public AsyncRelayCommand ChangeThemeCommand { get; }

    public SettingsViewModel(
        ICommonServices commonServices,
        ILogger<SettingsViewModel> logger)
        : base(commonServices, logger)
    {
        ChangeThemeCommand = new AsyncRelayCommand(ChangeThemeAsync);
    }

    private async Task ChangeThemeAsync()
    {
        // Show theme selection dialog
        await CommonServices.DialogService
            .ShowDialogAsync<ThemeWindow, ThemeViewModel, ThemeStyle>();
    }
}

3. Language Selection

Provide multi-language support using the LanguageViewModel:

using ISynergy.Framework.Core.Enumerations;
using ISynergy.Framework.UI.ViewModels;

public class LanguageWindow : Window
{
    public LanguageWindow()
    {
        InitializeComponent();
    }
}

// In your application
public class SettingsViewModel : ViewModel
{
    public AsyncRelayCommand ChangeLanguageCommand { get; }

    public SettingsViewModel(
        ICommonServices commonServices,
        ILogger<SettingsViewModel> logger)
        : base(commonServices, logger)
    {
        ChangeLanguageCommand = new AsyncRelayCommand(ChangeLanguageAsync);
    }

    private async Task ChangeLanguageAsync()
    {
        // Show language selection dialog
        await CommonServices.DialogService
            .ShowDialogAsync<LanguageWindow, LanguageViewModel, Languages>();
    }
}

4. Token Storage Service

Securely store and retrieve authentication tokens:

using ISynergy.Framework.UI.Abstractions.Services;

public class AuthenticationService
{
    private readonly ITokenStorageService _tokenStorage;

    public AuthenticationService(ITokenStorageService tokenStorage)
    {
        _tokenStorage = tokenStorage;
    }

    public async Task<bool> LoginAsync(string username, string password)
    {
        // Perform authentication
        var token = await _authApi.LoginAsync(username, password);

        if (token is not null)
        {
            // Store tokens securely
            await _tokenStorage.StoreTokenAsync("access_token", token.AccessToken);
            await _tokenStorage.StoreTokenAsync("refresh_token", token.RefreshToken);
            return true;
        }

        return false;
    }

    public async Task<string> GetAccessTokenAsync()
    {
        return await _tokenStorage.GetTokenAsync("access_token");
    }

    public async Task LogoutAsync()
    {
        await _tokenStorage.ClearAllTokensAsync();
    }
}

Usage Examples

Splash Screen Configuration

Configure splash screen behavior for your application:

using ISynergy.Framework.UI.Options;
using ISynergy.Framework.UI.Enumerations;

public void ConfigureServices(IServiceCollection services)
{
    services.Configure<SplashScreenOptions>(options =>
    {
        options.Type = SplashScreenTypes.Extended;
        options.DisplayDuration = TimeSpan.FromSeconds(3);
        options.MinimumDisplayTime = TimeSpan.FromSeconds(1);
    });
}

Assembly Registration

Register views, viewmodels, and windows from assemblies:

using ISynergy.Framework.UI.Extensions;

public void ConfigureServices(IServiceCollection services)
{
    var mainAssembly = Assembly.GetExecutingAssembly();

    // Register all views, viewmodels, and windows from assembly
    services.RegisterAssemblies(
        mainAssembly,
        assemblyName => assemblyName.Name.StartsWith("MyApp"));
}

Extension Methods

The UI framework provides several useful extension methods:

using ISynergy.Framework.UI.Extensions;

// Credential extensions
var credential = new Credential { Username = "user", Password = "pass" };
string base64 = credential.ToBase64();
var decoded = base64.FromBase64ToCredential();

// DateTime extensions
var now = DateTimeOffset.Now;
string formatted = now.ToLocalString(languageService);
string dateOnly = now.ToLocalDateString(languageService);

// Decimal extensions
decimal value = 1234.56m;
string currency = value.ToCurrency(languageService);
string number = value.ToNumeric(languageService);

// Language extensions
var german = Languages.German;
CultureInfo culture = german.GetCulture();
string displayName = german.GetDescription();

// Telemetry extensions
var exception = new InvalidOperationException("Something failed");
exception.Track(); // Tracks exception in telemetry

Configuration

Dependency Injection Setup

Platform-specific setup varies, but the core pattern is:

using ISynergy.Framework.Core.Abstractions.Services;
using ISynergy.Framework.Core.Services;
using ISynergy.Framework.UI.Abstractions.Providers;
using ISynergy.Framework.UI.Providers;
using ISynergy.Framework.UI.ViewModels;

public void ConfigureServices(IServiceCollection services)
{
    // Core services
    services.AddSingleton<ILanguageService, LanguageService>();
    services.AddSingleton<IInfoService, InfoService>();
    services.AddSingleton<IMessengerService, MessengerService>();

    // UI services
    services.AddSingleton<ITokenStorageService, TokenStorageService>();
    services.AddScoped<IAuthenticationProvider, AuthenticationProvider>();

    // ViewModels
    services.AddTransient<ThemeViewModel>();
    services.AddTransient<LanguageViewModel>();

    // Platform-specific services (implemented in UI.WPF, UI.MAUI, etc.)
    // services.AddSingleton<IDialogService, DialogService>();
    // services.AddSingleton<INavigationService, NavigationService>();
    // services.AddSingleton<IThemeService, ThemeService>();
}

Best Practices

Authentication Provider Usage

• Implement IAuthenticationProvider for centralized authorization
• Use it in command CanExecute delegates
• Bind UI element visibility to authorization checks
• Keep authorization logic testable and maintainable

Theme Management

• Store theme preferences in ISettingsService
• Use ThemeViewModel for user-facing theme selection
• Apply themes through platform-specific IThemeService
• Support both light and dark themes
• Allow custom accent colors

Token Storage

• Never store tokens in plain text
• Use ITokenStorageService for all credentials
• Clear tokens on logout
• Implement token refresh logic
• Handle token expiration gracefully
