ASP.NET Task Async WaitingForActivation

I am trying to send a post request to a third party API and retrieve the UserToken. Here is the code that does that:

private async Task<string> GetUserToken()
using (var client = new HttpClient())
var parameters = new Dictionary<string, string>
{"grant_type", "client_credentials" },
{"client_id", _clientId },
{"client_secret", _clientSecret }
var content = new FormUrlEncodedContent(parameters);

var response = await client.PostAsync(_baseUrl, content);
var responseString = await response.Content.ReadAsStringAsync();
UserTokenModel userToken = JsonConvert.DeserializeObject<UserTokenModel>(responseString);
return userToken.access_token;

When I test this in a console application, it prints out the correct UserToken value. However, when I do a method call to this method and step through it in the debugger, the value of the Usertoken is set

var userToken = GetUserToken();

Status: WaitingForActivation


Result:"{Not yet Computed}"

I'm not really sure why this is happening, but as a result, the value when used in other methods isn't set to the proper value. Any help would be greatly appreciated!


GetUserToken() does not return a user token. It returns a Task which represents asynchronous work whose result is the user token.

In essence, the following code:

var userToken = GetUserToken();

... is rather meaningless.

What you really want is:

var userToken = await GetUserToken();
// Do something with the token.
