Introduction

Lemon.ModuleNavigation

A lightweight module navigation framework built on top of the Microsoft Dependency Injection (MSDI) for AvaloniaUI, WPF and .net-xaml-platforms else. Support native aot (Avaloniaui)

Lemon.ModuleNavigation.AvaloniaUI

Extending Lemon.ModuleNavigation, this package provides handy NavigationContainers specifically designed for AvaloniaUI.

Key Advantages:

• Lightweight: Minimal performance overhead.
• Commonly module options are provided:LoadonDemand; Unload; Multi-Instance.
• Few dependencies: Only relies on Microsoft.Extensions.DependencyInjection.Abstractions.
• Framework Agnostic: Does not enforce any specific MVVM framework, allowing developers to use the MVVM framework of their choice.
• Highly Extensible: Easily customizable to suit specific needs.
• Simple to Use.

Usage:

Create module with View and ViewModel

Module.cs

using System;
using Lemon.ModuleNavigation.Avaloniaui;

namespace Lemon.ModuleNavigation.Sample.ModuleAs
{
    public class ModuleA : AvaModule<ViewA, ViewModelA>
    {
        public ModuleA(IServiceProvider serviceProvider) : base(serviceProvider)
        {

        }

        /// <summary>
        /// Specifies whether this module needs to be loaded on demand
        /// Default value is True
        /// </summary>
        public override bool LoadOnDemand => false;

        /// <summary>
        /// Alias of module for displaying usually
        /// Default value is class name of Module
        /// </summary>
        public override string? Alias => base.Alias;

        /// <summary>
        /// Specifies whether this module allow multiple instances
        /// If true,every navigation to this module will generate a new instance.
        /// Default value is false.
        /// </summary>
        public override bool ForceNew => base.ForceNew;

        /// <summary>
        /// Specifies whether this module can be unloaded.
        /// Default value is false.
        /// </summary>
        public override bool CanUnload => base.CanUnload;

        /// <summary>
        /// Initialize
        /// </summary>
        public override void Initialize()
        {
            base.Initialize();
        }
    }
}

View.cs

using Avalonia.Controls;
using Lemon.ModuleNavigation.Abstracts;

namespace Lemon.ModuleNavigation.Sample.ModuleAs;

public partial class ViewA : UserControl, IView

        InitializeComponent();
    }
}

ViewModel.cs

using Lemon.ModuleNavigation.Abstracts;
using Lemon.ModuleNavigation.Sample.ViewModels;

{
    public class ViewModelA :  IViewModel
    {
        public void Dispose()
        {
	        
        }
    }
}

In MainView.axaml or MainWindow.axaml

        // module navigation
        hostBuilder.Services.AddAvaNavigationSupport();
        // modules
        hostBuilder.Services.AddModule<ModuleA>();
        hostBuilder.Services.AddModule<ModuleB>();
        hostBuilder.Services.AddModule<ModuleC>();
        // views
        hostBuilder.Services.AddView<ViewAlpha, ViewAlphaViewModel>(nameof(ViewAlpha));
        hostBuilder.Services.AddView<ViewBeta, ViewBetaViewModel>(nameof(ViewAlpha));

简介

Lemon.ModuleNavigation

Lemon.ModuleNavigation 是一个基于微软依赖注入（MSDI）的轻量级模块导航框架，专为 AvaloniaUI、WPF 和其他 .NET XAML 平台设计。它支持 Native AOT，为 AvaloniaUI 提供高效的导航，性能开销极低。

Lemon.ModuleNavigation.AvaloniaUI

Lemon.ModuleNavigation 的扩展包，专为 AvaloniaUI 提供特定的 NavigationContainers，使得模块导航更加无缝且灵活。

主要优势：

• 轻量级：最小的性能开销。
• 依赖少：只依赖 Microsoft.Extensions.DependencyInjection.Abstractions。
• 框架无关：不强制使用任何特定的 MVVM 框架，允许开发者选择自己喜欢的 MVVM 框架。
• 高度可扩展：可以轻松定制以满足特定需求。
• 简单易用。
