我WPF專案中還有開一個API 讓使用者可以call網址 直接觸發撥放的部分
用 Caliburn.Micro 框架
用POSTMAN測試 寫法1 回傳 415 寫法2 回傳 500
目前問題是 ApiController 吃不到DI的function
程式碼
bootstrapper.cs

public partial class Bootstrapper : BootstrapperBase
{
    private readonly SimpleContainer _container = new SimpleContainer();
    public Bootstrapper()
    {
        Initialize();
    }
    protected override void Configure()
    {
        _container.Singleton<MainViewModel>();
    }

    protected override void OnStartup(object sender, StartupEventArgs e)
    {
        DisplayRootViewForAsync<LoginViewModel>();
    }
}

MainViewModel.cs

        api = new ApiController(this);

        Play(true);

apiController.cs

using Microsoft.AspNetCore.Mvc;

//輸出 System.InvalidOperationException: Unable to resolve service for type 'ViewModels.MainViewModel' while attempting to activate 'Controller.ApiController'.
