HttpClient未将请求发送到Web Api异步get方法

Question

I haven't used Web Api in a while and I am stuck with something that should be very simple.

I have an asynchronous get method in a Web Api controller:

public class SomeController : ApiController  
{  
   [HttpGet]  
   public async Task<IHttpActionResult> MyMethodAsync(Guid id)  
   {  
      //... doing something.
   }  
}

On my client application I am trying to call it like so:

using(var client = new HttpClient())
{
   var result = client.GetAsync($"{url}/Some/MyMethodAsync/{Guid.NewGuid()}"); 
   //I have tried making the above call with and without await
   //since I saw in some other post that it is not needed.

   //.... doing something else.

   //This POST method does stop in the beak point I set inside of it.
   var result2 = client.PostAsync($"{url}/Some/MyPostAsync", someContent);
}

The problem that I have is that it seems that the request is not even being sent to the Web Api since the break point that I am setting on MyMethodAsync has the warning that the symbols are not being loaded.

What really confuses me is that the next call is to a POST method on the same controller that when I call it the symbols load and its breakpoint gets hit.

Like I said, I am comming back to Web Api after a really long time and quite a few things are fuzzy in my mind. I only have the default route so, I do not know if I have to add more specific routes and if so, how to specify them.

As a side note I have two other GET methods that also have a Guid parameter. I have tried calling those with the same result.

Thank you for your help.

UPDATE : To make matters more confusing. If I run the application but instead of using the client I open a browser and enter the url exactly as the client would do it, the break point in the action gets hit. Right after that I try using the client and then it won't.

Answer 1

1. Open App_Start / WebApiConfig.cs

2. Add New Route

config.Routes.MapHttpRoute(
    name: "NewRoute",
    routeTemplate: "api/{controller}/{action}/{id}",
    defaults: new { id = RouteParameter.Optional }
);

2.1. FULL Code

3. USE Action Name Attribute [ActionName("MyMethod1")]

    [ActionName("MyMethod1")]
    [HttpGet]
    public IHttpActionResult MyMethod1(Guid id)
    {
        return Ok<string>($" ok MyMethod1 and id= {id}");

    }

4. Same for MyMethod2

    [ActionName("MyMethod2")]
    [HttpGet]
    public IHttpActionResult MyMethod2(Guid id)
    {
        return Ok<string>($" ok MyMethod2 and id= {id}");

    }

Extra Note : For the symbols are not being delete error in visual studio

• close visual studio
• Delete WebApplication1\\bin
• Delete WebApplication1\\obj
