想法是主程序尽量的简单，其他的尽量按需调用。

所以把Demo这个主程序的内容大部分移到LunZi.Common项目去了。

1. Demo的MauiProgram

     public static MauiApp CreateMauiApp()
     {
   
         try
         {
             var assembly = AssemblyLoadContext.Default.LoadFromAssemblyPath(@"C:\Plugin\windows\LunZi.Common.dll");
   
             var type = assembly.GetType("LunZi.Common.MauiProgram");
             var method = type!.GetMethod("CreateMauiApp", BindingFlags.Static | BindingFlags.Public);
             var app = (MauiApp)method!.Invoke(null, null)!;
             return app;
         }
         catch (Exception ex)
         {
   
             var builder = MauiApp.CreateBuilder();
             builder.UseMauiApp<App>();
   
             var msg = ex.Message + "\r\n" + ex.StackTrace;
             if (ex.InnerException != null)
                 msg += "\r\n-----------InnerException--------------------\r\n" + ex.InnerException.ToString();
   
             builder.Services.AddSingleton(ii => new MainPage(msg));
             return builder.Build();
         }
     }
   
   

2. LunZi.Common的MauiProgram

     public static class MauiProgram
     {
         public static List<string> AssemblyNames { get; set; } = new();
         public static MauiApp CreateMauiApp()
         {
             AppDomain.CurrentDomain.AssemblyResolve += CurrentDomain_AssemblyResolve;
   
             return Create();
         }
   
         private static MauiApp Create()
         {
             var builder = MauiApp.CreateBuilder();
             builder
                 .UseMauiApp<App>()
                 .UseMauiCommunityToolkit()
                 .UseMauiCommunityToolkitMarkup()
             .ConfigureFonts(fonts =>
             {
                 fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
                 fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
             });
   
   
             builder.AddLunZiService();
             var app = builder.Build();
             app.InitializeLunZi();
             return app;
         }
   
   
         private static Assembly? CurrentDomain_AssemblyResolve(object? sender, ResolveEventArgs args)
         {
             var name = args.Name.Split(',')[0].Trim();
   
             string fullName = Path.Combine(@"c:\plugin\packages", name.EndsWith(".resources") ? Thread.CurrentThread.CurrentCulture.Name : "", name + ".dll");
             if (File.Exists(fullName))
             {
                 AssemblyNames.Add(name);
                 return AssemblyLoadContext.Default.LoadFromAssemblyPath(fullName);
             }
             else
                 return default;
         }
     }
   
   

以后Demo将基本不动，只要修改LunZi.Common，增加其他类库。想着公司刚好要开发Maui的程序，接一下就以公司产品为例，折腾折腾这个插件开发。

哦，我公司是开发酒店自助入住程序的，所以将会有这么一些插件
