UnloadWorkflow Yukarıdaki kodda çağrılan yöntem, yeni bir iş akışının yüklenmesine hazırlanmak için şu anda yüklü olan bir iş akışını kaldırır ve aşağıdaki gibi uygulanır:

private void UnloadWorkflow()
{
    IDesignerHost designerHost = GetService(typeof(IDesignerHost)) as IDesignerHost;
    if (designerHost != null && designerHost.Container.Components.Count > 0)
        WorkflowLoader.DestroyObjectGraphFromDesignerHost(designerHost, designerHost.RootComponent as Activity);

    if (this.designSurface != null)
    {
        this.designSurface.Dispose();
        this.designSurface = null;
    }

    if (this.workflowView != null)
    {
        Controls.Remove(this.workflowView);
        this.workflowView.Dispose();
        this.workflowView = null;
    }
}

Private Sub UnloadWorkflow()


    Dim designerHost As IDesignerHost = CType(GetService(GetType(IDesignerHost)), IDesignerHost)
    If designerHost IsNot Nothing And designerHost.Container.Components.Count > 0 Then
        WorkflowLoader.DestroyObjectGraphFromDesignerHost(designerHost, CType(designerHost.RootComponent, Activity))
    End If

    If Me.designSurface IsNot Nothing Then
        Me.designSurface.Dispose()
        Me.designSurface = Nothing
    End If


    If Me.workflowView IsNot Nothing Then
        Controls.Remove(Me.workflowView)
        Me.workflowView.Dispose()
        Me.workflowView = Nothing
    End If

End Sub
