❔ httpClient.PostAsync() - Program exits and never hits my breakpoint after?

This is the code:

    public async Task<string> RegisterAgent(string symbol, string faction)
    { 
        string url = apiUrl + "register";
        AgentRequest newAgent = new AgentRequest(symbol, faction);

        var content = JsonContent.Create(newAgent, mediaTypeHeaderValue);
        var response = await httpClient.PostAsync(url, content);
        response.EnsureSuccessStatusCode();

        System.Console.WriteLine(response.Content);
        return "";
    }

    public async Task<string> RegisterAgent(string symbol, string faction)
    { 
        string url = apiUrl + "register";
        AgentRequest newAgent = new AgentRequest(symbol, faction);

        var content = JsonContent.Create(newAgent, mediaTypeHeaderValue);
        var response = await httpClient.PostAsync(url, content);
        response.EnsureSuccessStatusCode();

        System.Console.WriteLine(response.Content);
        return "";
    }

    public async Task<string> RegisterAgent(string symbol, string faction)
    { 
        string url = apiUrl + "register";
        AgentRequest newAgent = new AgentRequest(symbol, faction);

        var content = JsonContent.Create(newAgent, mediaTypeHeaderValue);
        var response = await httpClient.PostAsync(url, content);
        response.EnsureSuccessStatusCode();

        System.Console.WriteLine(response.Content);
        return "";
    }

    public async Task<string> RegisterAgent(string symbol, string faction)
    { 
        string url = apiUrl + "register";
        AgentRequest newAgent = new AgentRequest(symbol, faction);

        var content = JsonContent.Create(newAgent, mediaTypeHeaderValue);
        var response = await httpClient.PostAsync(url, content);
        response.EnsureSuccessStatusCode();

        System.Console.WriteLine(response.Content);
        return "";
    }

When I step through the code with my debugger it gets as far as

var response...

var response...

var response...

var response... and then the application exits.... It should get to the code below.

I don't know if this changes things but core is a class in a Class Library. I am using a Unit Test to run the test.

Sorry if this is a really stupid question but I'm stumped.

I have just realised that the Unit Test file was still called Core.csCore.cs

I changed the Unit Test class to CoreUTCoreUT to avoid any naming confusion. I've now renamed the .cs file and rebuilt the application but it's still exiting on the PostAsync()....

Ok not sure exactly what I did but it's working now... I changed the return in the function from """" to the string symbolsymbol andalso changed the unit test to use Assert.Equal()Assert.Equal(). I can see it now gets past PostAsync()PostAsync() and is now throwing an error due to response.EnsureSuccessStatusCode();response.EnsureSuccessStatusCode(); not returning 200.

I have to go to bed now but will leave this up as I'm not sure what I previously did wrong. Any advise would be great and I'll pick it up in the morning, thanks!
