ASP.NET Core 2.2 Web API 未命中任何已配置的路由，这是为什么？

Question

I have created BaseController that looks like this

`[ApiController]
  public class MoviesPlaceBaseController : ControllerBase
  {
    protected readonly IMoviesPlaceSupervisor _moviesPlaceSupervisor;

    public MoviesPlaceBaseController(IMoviesPlaceSupervisor moviesPlaceSupervisor)    
    {
        _moviesPlaceSupervisor = moviesPlaceSupervisor;
    }`

In my "PostController" I derive from that base controller class which looks like this

`    [Route("[controller]")]
    [Produces("application/json")]
    public class PostController : MoviesPlaceBaseController
    {
      public PostController(IMoviesPlaceSupervisor supervisor) : base (supervisor){ }

        // GET api/post
        [HttpGet]
        [Produces(typeof(List<PostViewModel>))]
        public async Task<ActionResult<List<PostViewModel>>> Get(CancellationToken ct = default(CancellationToken))
        {
          return new ObjectResult(await _moviesPlaceSupervisor.GetAllPostsAsync(ct));
        }`

My launchSettings.json I removed the https url and it now looks like this

`"MoviesPlaceAPI": {
      "commandName": "Project",
      "launchBrowser": true,
      "launchUrl": "api/",
      "applicationUrl": "http://localhost:5000",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }`

my Startup.cs ConfigureServices looks like this

` public void ConfigureServices(IServiceCollection services)
    {
      services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

      services.AddConnectionProvider(Configuration)
        .ConfigureSupervisor()
        .AddMiddleware()
        .AddCorsConfiguration()
        .ConfigureRepositories();
    }`

When running my application I cannot hit my api/post route. When I put break points in that action and run the app, the breakpoint says its "unverified". I tried doing api/post and api/posts. In the controller class i removed the Route["controller"] with just the name of the controller "post", but same thing. The weird thing is that I can hit api/values just fine, even though that controller no longer exists in my app. I have no idea what is going on, can someone shed some light please.

I upgraded my project from asp.net core 2.1 to 2.2 When I performed clean then build. It did not entirely get rid of the previously compiled code. My launch.json file was still pointing to Debug/netcoreapp.2.1... after changing that to 2.2 everything started working as expected.
