public interface IModelClassFactoryIn this example, we create a generic interface for creating instances of a model class. We then create a class that implements this interface for a specific model class. Finally, we use the factory to create an instance of the model. The package library for IModelClassFactory is likely to be included in a larger package related to building and running C# applications. Some possibilities include .NET Core, .NET Framework, and Xamarin.where T : class, new() { T CreateInstance(); } public class MyModelClassFactory : IModelClassFactory { public MyModel CreateInstance() { return new MyModel(); } } var factory = new MyModelClassFactory(); var myModel = factory.CreateInstance();
