SyncStagedProgressEventArgs converted to DbSyncSessionProgressEventArgs

Question

I am working on an app that is using Synchronization Framework v2. I am basically done with it, but would like to offer some better fedback about the progress of the synchronization. I was looking at one of the Synchframework examples that Microsoft offers, SharingAppDemo-CEProviderEndToEnd, and see that the have a method in the ProgressForm that takes a SyncStagedProgressEventArgs and converts it to DbSyncSessionProgressEventArgs which makes sense because DbSyncSessionProgressEventArgs inherits from SyncStagedProgressEventArgs, but when I try this I always get an error saying that implicit conversion failed.

Am I missing something or is this conversion really not possible?

Thanks!

Method in ProgressForm

public void ProgressChanged(SyncStagedProgressEventArgs args)
    {
        string message = "";
        listSyncProgress.Items.Add(message);
        try
        {
            DbSyncSessionProgressEventArgs sessionProgress = (DbSyncSessionProgressEventArgs)args;
            DbSyncScopeProgress progress = sessionProgress.GroupProgress;
            switch (sessionProgress.DbSyncStage)
            {
                case DbSyncStage.SelectingChanges:
                    message += "Sync Stage: Selecting Changes";
                    listSyncProgress.Items.Add(message);
                    foreach (DbSyncTableProgress tableProgress in progress.TablesProgress)
                    {
                        message = "Enumerated changes for table: " + tableProgress.TableName;
                        message += "[Inserts:" + tableProgress.Inserts.ToString() + "/Updates :" + tableProgress.Updates.ToString() + "/Deletes :" + tableProgress.Deletes.ToString() + "]";
                        listSyncProgress.Items.Add(message);
                    }
                    break;
                case DbSyncStage.ApplyingChanges:
                    message += "Sync Stage: Applying Changes";
                    listSyncProgress.Items.Add(message);
                    foreach (DbSyncTableProgress tableProgress in progress.TablesProgress)
                    {
                        message = "Applied changes for table: " + tableProgress.TableName;
                        message += "[Inserts:" + tableProgress.Inserts.ToString() + "/Updates :" + tableProgress.Updates.ToString() + "/Deletes :" + tableProgress.Deletes.ToString() + "]";
                        listSyncProgress.Items.Add(message);
                    }
                    break;
                default:
                    break;
            }

            message = "Total Changes : " + progress.TotalChanges.ToString() + "  Inserts :" + progress.TotalInserts.ToString();
            message += "  Updates :" + progress.TotalUpdates.ToString() + "  Deletes :" + progress.TotalDeletes.ToString();
            listSyncProgress.Items.Add(message);

        }
        catch (Exception e)
        {
            throw e;
        }

        message = "Completed : " + args.CompletedWork + "%";
        listSyncProgress.Items.Add(message);

        Application.DoEvents();
    }
