Get Azure Active Directory Token with username and password

Question

I'm trying to authenticate my client using AAD and automate this using a Windows Service. In AAD .NET SDK, There's two methods, AcquireTokenAsync and AcquireToken, but i can't use either of these methods, the await call will stay forever with no response, and when i do something like this:

result = authContext.AcquireTokenAsync(resourceHostUri, clientId, new UserCredential(hardcodedUsername, hardcodedPassword)).Result;

The object returns a status of Waiting for Activation & Code 31..

Now, Is there anyway to acquire the token using hardcoded username and password?

My full code:

        string hardcodedUsername = "username";
        string hardcodedPassword = "password";

        string tenant = "[email protected]";
        string clientId = "clientId";
        string resourceHostUri = "https://management.azure.com/";
        string aadInstance = "https://login.microsoftonline.com/{0}";

        string authority = String.Format(CultureInfo.InvariantCulture, aadInstance, tenant);


        authContext = new AuthenticationContext(authority);

        AuthenticationResult result = null;
            try
            {

                result = authContext.AcquireTokenAsync(resourceHostUri, clientId, new UserCredential(hardcodedUsername, hardcodedPassword)).Result;
            }
            catch (Exception ex)
            {
                System.Diagnostics.Debug.WriteLine(ex.Message);
            }

            return result;

I'm trying to get access to Azure API.

UPDATE 1:

I got this in the output when i tried to await the call, i think this might help:

Microsoft.IdentityModel.Clients.ActiveDirectory TokenCache: Looking up cache for a token... Microsoft.IdentityModel.Clients.ActiveDirectory TokenCache: No matching token was found in the cache Microsoft.IdentityModel.Clients.ActiveDirectory d__0: Sending user realm discovery request to 'https://login.microsoftonline.com/common/UserRealm/username?api-version=1.0' Microsoft.IdentityModel.Clients.ActiveDirectory d__4: User with hash '***' detected as 'Federated'
