Freezable.CreateInstanceCore Method

When implemented in a derived class, creates a new instance of the Freezable derived class.

Namespace:  System.Windows
Assembly:  WindowsBase (in WindowsBase.dll)

protected abstract Freezable CreateInstanceCore()

Return Value

Type: System.Windows.Freezable
The new instance.

Do not call this method directly (except when calling base in an implementation). This method is called internally by the CreateInstance method whenever a new instance of the Freezable is created.

Notes to Inheritors

Every Freezable derived class must implement this method. A typical implementation is to simply call the default constructor and return the result.

The following example shows a typical implementation of CreateInstanceCore.

public class MyFreezable : Freezable
{
    // Typical implementation of CreateInstanceCore 
    protected override Freezable CreateInstanceCore()
    {

        return new MyFreezable();      
    }


    // ... 
    // Other code for the MyFreezableClass. 
    // ...


}
