开发环境：VS2022、.NET6

1、创建项目：MyWpfApp，这里不再废话了。

2、NuGet添加：

2.1、Volo.Abp.Autofac

2.2、Serilog.Sinks.File

2.3、Serilog.Sinks.Async

2.4、Serilog.Extensions.Logging

2.5、Serilog.Extensions.Hosting

2.6、Microsoft.Extensions.Hosting

，如下图所示：

3、开始写代码

3.1、创建MyWpfAppModule.cs

using Microsoft.Extensions.DependencyInjection;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Volo.Abp.Autofac;
using Volo.Abp.Modularity;namespace MyWpfApp
{[DependsOn(typeof(AbpAutofacModule))]internal class MyWpfAppModule:AbpModule{public override void ConfigureServices(ServiceConfigurationContext context){context.Services.AddSingleton<MainWindow>();}}
}

3.2、创建 HelloWorldService.cs

using Microsoft.Extensions.Logging;
using Microsoft.Extensions.Logging.Abstractions;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Volo.Abp.DependencyInjection;namespace MyWpfApp
{public class HelloWorldService:ITransientDependency{public ILogger<HelloWorldService> Logger { get; set; }public HelloWorldService(){Logger=NullLogger<HelloWorldService>.Instance;}public string SayHello(){Logger.LogInformation("Call SayHello");return "Hello world";}}
}

3.3、修改MainWindow.xaml.cs和MainWindow.xaml

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;namespace MyWpfApp
{/// <summary>/// Interaction logic for MainWindow.xaml/// </summary>public partial class MainWindow : Window{private readonly HelloWorldService _helloWorldService;public MainWindow(){_helloWorldService = new HelloWorldService();InitializeComponent();}protected override void OnContentRendered(EventArgs e){HelloLabel.Content = _helloWorldService.SayHello();}}
}

<Window x:Class="MyWpfApp.MainWindow"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:d="http://schemas.microsoft.com/expression/blend/2008"xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"xmlns:local="clr-namespace:MyWpfApp"mc:Ignorable="d"Title="MainWindow" Height="450" Width="800"><Grid><Label Name="HelloLabel" FontSize="90" Margin="58,129,-58,-129"/></Grid>
</Window>

3.4、修改App.xaml.cs

using Microsoft.Extensions.DependencyInjection;
using Serilog;
using Serilog.Events;
using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Threading.Tasks;
using System.Windows;
using Volo.Abp;namespace MyWpfApp
{/// <summary>/// Interaction logic for App.xaml/// </summary>public partial class App : Application{private IAbpApplicationWithInternalServiceProvider? _abpApplication;protected override async void OnStartup(StartupEventArgs e){Log.Logger = new LoggerConfiguration()
#if DEBUG.MinimumLevel.Debug()
#else.MinimumLevel.Information()
#endif.MinimumLevel.Override("Microsoft", LogEventLevel.Information).Enrich.FromLogContext().WriteTo.Async(c => c.File("Logs/logs.txt")).CreateLogger();try{Log.Information("Starting WPF host");_abpApplication = await AbpApplicationFactory.CreateAsync<MyWpfAppModule>(options =>{options.UseAutofac();options.Services.AddLogging(loggingBuilder => loggingBuilder.AddSerilog(dispose: true));});await _abpApplication.InitializeAsync();//此处注释由于_abpApplication未初始化，OnExit会报错//_abpApplication.Services.GetRequiredService<MainWindow>()?.Show(); //这里解除注释后会弹出两个MainWindow界面}catch (Exception ex){Log.Fatal(ex, "Host terminated unexpectedly!");}}protected override async void OnExit(ExitEventArgs e){if (_abpApplication != null){await _abpApplication.ShutdownAsync();}Log.CloseAndFlush();}}
}
