Here is an example of the code you need to handle contact post activations for Facebook Ids:

protected override void OnActivated(IActivatedEventArgs args)
    if (args.Kind == ActivationKind.Contact)
        var contactArgs = args as IContactActivatedEventArgs;
        if (contactArgs.Verb == Windows.ApplicationModel.Contacts.ContactLaunchActionVerbs.Post)
            IContactPostActivatedEventArgs postArgs = contactArgs as IContactPostActivatedEventArgs;

     //get contact display info
     var contactName = postArgs.Contact.DisplayName;
            var contactThumbnail = postArgs.Contact.Thumbnail;

            if (postArgs.ServiceId == "")
                var userId = postArgs.ServiceUserId;
                //add posting logic for Facebook Ids

void App::OnActivated(IActivatedEventArgs^ args)
 if (args->Kind == ActivationKind::Contact)
  auto contactArgs = dynamic_cast<IContactActivatedEventArgs^>(args);
  if (contactArgs->Verb == Windows::ApplicationModel::Contacts::ContactLaunchActionVerbs::Post)
   auto postArgs = dynamic_cast<ContactPostActivatedEventArgs^>(contactArgs);

       //get contact display info
auto contactName = postArgs->Contact->DisplayName;
   auto contactThumbnail = postArgs->Contact->Thumbnail;

   if (postArgs->ServiceId == "")
    auto userId = postArgs->ServiceUserId;
    //add posting logic for Facebook Ids


Windows 8.1 allows users to post to their contacts from the Contact Card or Windows Search experience. By implementing the contact post activation contract, Windows can launch your app to post for the user.

To receive post activations, your app must register for the "" extension category in its manifest. Under this extension, you must include a "LaunchAction" element with the "Verb" attribute equal to "post." You can then specify the "ServiceId" element to specify the domain name of the service that your app can post to, for example ""

If multiple apps have registered for this contract, the user can choose one of them as their default for handling posting.

Here is an example for manifest registration:

<m2:Extension Category="" xmlns:m2="">
      <m2:LaunchAction Verb="post" DesiredView="useLess">

After you register in your manifest, your app can be activated for the contact post contract. When your app is activated, you can use the event information to identify the post activation and extract the parameters that help you complete the post scenario for the user.


Contact Contact Contact Contact

Gets the contact for the post.

public : Contact Contact { get; }
public Contact Contact { get; }
Public ReadOnly Property Contact As Contact
var contact =;
Contact Contact Contact Contact

The contact for the post.


Use the Contact property to collect additional info about the contact that is being posted to. The contact can have a name and thumbnail that can be used to represent it in your app’s UI. Or, the contact can have alternative user ids that can be used in case the primary user id is unavailable. The ConnectedServiceAccounts property contains a list of all services available for the contact. You can use the ContactConnectedServiceAccount.Id property on each service to retrieve alternative user ids.


For post activations, the ConnectedServiceAccounts property is only populated with services that match the primary service that the activation was originally invoked for.

Here are possible Contact properties that can be populated during a post activation:

Kind Kind Kind Kind

Gets the activation type.

public : ActivationKind Kind { get; }
public ActivationKind Kind { get; }
Public ReadOnly Property Kind As ActivationKind
var activationKind = contactPostActivatedEventArgs.kind;

Gets the execution state of the app before it was activated.

public : ApplicationExecutionState PreviousExecutionState { get; }
public ApplicationExecutionState PreviousExecutionState { get; }
Public ReadOnly Property PreviousExecutionState As ApplicationExecutionState
var applicationExecutionState = contactPostActivatedEventArgs.previousExecutionState;

ServiceId ServiceId ServiceId ServiceId

public string ServiceId { get; }
Public ReadOnly Property ServiceId As string

The identifier of the service used for the post.


Your app will only receive post activations for ServiceIds that match the "ServiceId" elements that your app has registered in its manifest.

ServiceUserId ServiceUserId ServiceUserId ServiceUserId

Gets the user identifier of the service used for the post.

public : Platform::String ServiceUserId { get; }
public string ServiceUserId { get; }
Public ReadOnly Property ServiceUserId As string
