Os exemplos de C# e Visual Basic Scripting Edition (VBScript) a seguir demonstram a exportação da configuração de uma máquina virtual. Exemplos que mostram a exportação de uma máquina virtual podem ser encontrados nos tópicos ExportSystemDefinition e Exporting a instantâneo de uma máquina virtual.
Os utilitários C# referenciados podem ser encontrados em Utilitários comuns para os exemplos de virtualização (V2).
