[SecurityCriticalAttribute]
public void RefreshDataAsync(
	object userToken
)

Parameters

userToken
Type: System.Object

User-specified state object that is passed to the delegate when this method completes the operation.

Exception Condition
ObjectDisposedException

ArgumentNullException

The userToken argument specifies null.

PeerToPeerException

The prior RefreshDataAsync call has not yet completed.

The data retrieved is stored in a cache accessed by the GetApplications and GetObjects methods as well as the PresenceStatus property. The InternalRefreshData method only needs to be used if the caller is not subscribed to the specified Peer, PeerNearMe, or PeerContact.

This method blocks additional calls until the network operation is complete and cache has been updated.

The caller is not required to sign in with the SignIn method or via a user interface in to complete this operation successfully.
