Web Service Set User License Office 365

Question

So basically, I want to set AD's user license (Powershell script) from C# code. Here is the code:

//adminUser & adminPassword from app.config

    public static string SetUserLicense(string userPrincipalName, string adminUser, SecureString adminPassword, string licenses)
            {
                string strReturn = "";
                try
                {
                    // Create Initial Session State for runspace.
                    InitialSessionState initialSession = InitialSessionState.CreateDefault();
                    initialSession.ImportPSModule(new[] { "MSOnline" });
                    // Create credential object.
                    PSCredential credential = new PSCredential(adminUser, adminPassword);
                    // Create command to connect office 365.
                    Command connectCommand = new Command("Connect-MsolService");
                    connectCommand.Parameters.Add((new CommandParameter("Credential", credential)));

                    Command userCommand = new Command("Set-MsolUser");
                    userCommand.Parameters.Add((new CommandParameter("UserPrincipalName", userPrincipalName)));
                    userCommand.Parameters.Add((new CommandParameter("UsageLocation", "ID")));

                    Command licCommand = new Command("Set-MsolUserLicense");
                    licCommand.Parameters.Add((new CommandParameter("UserPrincipalName", userPrincipalName)));
                    licCommand.Parameters.Add((new CommandParameter("AddLicenses", licenses)));

                    using (Runspace psRunSpace = RunspaceFactory.CreateRunspace(initialSession))
                    {
                        // Open runspace.
                        psRunSpace.Open();

                        //Iterate through each command and executes it.
                        foreach (var com in new Command[] { connectCommand, userCommand, licCommand })
                        {
                            if (com != null)
                            {
                                var pipe = psRunSpace.CreatePipeline();
                                pipe.Commands.Add(com);
                                // Execute command and generate results and errors (if any).
                                Collection<PSObject> results = pipe.Invoke();
                                var error = pipe.Error.ReadToEnd();
                                if (error.Count > 0 && com == licCommand)
                                {
                                    strReturn = error[0].ToString();
                                }
                                else if (results.Count >= 0 && com == licCommand)
                                {
                                    strReturn = "User License update successfully.";
                                }
                            }
                        }
                        // Close the runspace.
                        psRunSpace.Close();
                    }
                }
                catch (Exception ex)
                {

                    strReturn = ex.Message;
                }
                return strReturn;
            }

However, when I run it, everything works well (unlicensed now become licensed). Then, I published the code so I get the DLLs & Services.asmx which run on the server. After that, I make a service agent and added service reference (web service URL), so periodically, the agent can call SetUserLicense function.

Here is code from service agent which calls the Web Service:

NewWSOffice365.ServicesSoapClient Service = new NewWSOffice365.ServicesSoapClient();
string Result = Service.SetUserLicense("blabla@bns.org");

The problem is when the service agent runs, I get error:

You must call the Connect-MsolService cmdlet before calling any other cmdlets.

The weird thing, I've put Connect-MsolService in my C# code (see above). Everything meets its requirement, here: http://code.msdn.microsoft.com/office/Office-365-Manage-licenses-fb2c6413 and set IIS AppPool UserProfile to true (default: false).

You need to add Powershell session before using "Connect-MsolService" credential is your above credential.

PSCommand psSession = new PSCommand();
psSession.AddCommand("New-PSSession");
psSession.AddParameter("ConfigurationName", "Microsoft.Exchange");
psSession.AddParameter("ConnectionUri", new Uri("https://outlook.office365.com/powershell-liveid/"));
psSession.AddParameter("Credential", credential);
psSession.AddParameter("Authentication", "Basic");
psSession.AddParameter("AllowRedirection");

powershell.Commands = psSession;
powershell.Invoke();

PSCommand connect = new PSCommand();
connect.AddCommand("Connect-MsolService");
connect.AddParameter("Credential", credential);

powershell.Commands = connect;
powershell.Invoke();
