// T4 code generation is enabled for model 'C:\Users\Manuel\Documents\Repositories\zhaw-dnet2\Tasks\Lab9\EntityFramework\EF6\FlughafenModel.edmx'.
// To enable legacy code generation, change the value of the 'Code Generation Strategy' designer
// property to 'Legacy ObjectContext'. This property is available in the Properties Window when the model
// is open in the designer.
// If no context and entity classes have been generated, it may be because you created an empty model but
// have not yet chosen which version of Entity Framework to use. To generate a context class and entity
// classes for your model, open the model in the designer, right-click on the designer surface, and
// select 'Update Model from Database...', 'Generate Database from Model...', or 'Add Code Generation
