ASP.NET Core 3.0 專案樣版的預設相依注入服務研究分析

在這篇文章中，將會使用 Visual Studio 2019 來使用預設的專案樣板，使用 .NET Core 3.0 平台，依序建立起各個專案樣板中的 ASP.NET Core 的專案，接著，觀察這些專案中的預設相依性注入的服務有哪些。

為了要能夠了解到專案內的相依性注入容器內已經有哪些預設的服務已經注入完成，這裡需要取得 IServiceCollection 這個具體實作的物件，並且使用底下的方式，逐一取得相依性注入服務容器的各個已經註冊的型別對應關係。

foreach (var item in serviceDescriptors)
{
    var newObject = new ServiceRegistration()
    {
        Lifetime = item.Lifetime.ToString(),
        ServiceType = item.ServiceType.Name,
        ImplementationType = item.ImplementationType?.Name,
        ImplementationInstance = item.ImplementationInstance?.GetType().Name,
        ImplementationFactory = item.ImplementationFactory?.GetType().GenericTypeArguments[1].Name
        //ImplementationFactory = item.ImplementationFactory != null ? "Factory" : ""
    };
    list.Add(newObject);
}

其中，需要在 Startup 類別中宣告一個欄位 IServiceCollection Services，接著在 ConfigureServices 方法內，將傳入的 IServiceCollection 參數物件，設定給剛剛宣告好的 Services 欄位變數

最後，請在 Configure 方法內，將上述程式碼在這個方法內來執行，就可以取得現在相依性注入服務容器的各個型別對應註冊表了。

另外，在這篇文章中，也彙整了各種專案範本的 Program 與 Startup 類別的程式碼，大家可以參考與比對，在不同的專案範本中，這些程式碼的差異在哪裡呢？

空白的專案

請先使用 Visual Studio 2019 在 [建立新專案]對話窗中，選擇建立一個 [ASP.NET Core Web 應用程式]
在 [設定新的專案] 對話窗中，輸入適合的專案名稱
在 [建立新的 ASP.NET Core Web 應用程式] 對話窗中，請選擇 [空白] 專案樣版

可用於建立 ASP.NET Core 應用程式的空白專案範本，此範本不含任何內容
點選右下方 [建立] 按鈕，完成此專案範本的建立工作
現在可以開始執行這個專案，底下是這個專案的執行畫面截圖

這個專案的 Program 類別的程式碼為

    public class Program
    {
        public static void Main(string[] args)
        {
            CreateHostBuilder(args).Build().Run();
        }

        public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .ConfigureWebHostDefaults(webBuilder =>
                {
                    webBuilder.UseStartup<Startup>();
                });
    }

這個專案的 Startup 類別程式碼為

    public class Startup
    {
        // This method gets called by the runtime. Use this method to add services to the container.
        // For more information on how to configure your application, visit https://go.microsoft.com/fwlink/?LinkID=398940
        public void ConfigureServices(IServiceCollection services)
        {
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            app.UseRouting();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapGet("/", async context =>
                {
                    await context.Response.WriteAsync("Hello World!");
                });
            });
        }
    }

這裡是預設註冊的所有服務清單，總共有 71 個
