mvvm-light Getting started with mvvm-light ObservableObject

Example

The ObservableObject class contains some helpful methods to help with the MVVM pattern.

The RaisePropertyChanged provides a compile safe method to raise property changed events.
It can be called with

RaisePropertyChanged(() => MyProperty);

The Set method can be used in the property setter to set the new value and raise the property changed event (only if change occurred). It returns true if change occurred and false otherwise.
example usage:

private string _myValue;
public string MyValue    
{
    get { return _myValue; }
    set { Set(ref _myValue, value); }
}
