The ViewModel type exposes the following members.

Constructors

	Name	Description
	ViewModel	Default constructor

Properties

	Name	Description
	HasErrors	Gets a value that indicates whether the entity has validation errors.

Methods

	Name	Description
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetErrors	Gets all error messages of the specified property. If the propertyName is null all error messages will be returned.
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetPropertyErrors	Gets all error messages of the specified property. If the propertyName is null all error messages will be returned.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsValueValid<TValue>	Can be used to check whether a value is valid.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OnErrorsChanged	Raised when the validation state of the view model has changed (e.g. error added or removed).
	OnPropertyChanged	Method called to fire a PropertyChanged event. Also raises the PropertyChanged event to support binding.
	PropertyHasError	Checks whether the specified property has errors or is valid.
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	TrySetValue<TValue>(TValue, TValue, String)	Generic property setter. Sets the value of any property of the extending view model by passing in a the corresponding property backing field. Automatically raises the PropertyChanged event for this property.
	TrySetValue<TValue>(TValue, Func<TValue, ValueTuple<Boolean, IEnumerable<String>>>, TValue, Boolean, Boolean, String)	Sets the value of the referenced property and executes a validation delegate.
	TrySetValueSilent<TValue>(TValue, TValue, String)	Generic property setter. Silently sets the value of any property of the extending view model by passing in a the corresponding property backing field. Suppresses a PropertyChanged event for this property.
	TrySetValueSilent<TValue>(TValue, Func<TValue, ValueTuple<Boolean, IEnumerable<String>>>, TValue, Boolean, Boolean, String)	Silently sets the value of the referenced property without raising PropertyChanged and executes a validation delegate.

Events

	Name	Description
	ErrorsChanged	Occurs when the validation errors have changed for a property or for the entire entity.
	PropertyChanged	Event fired whenever a child property changes its value.
	PropertyValueChanged	PropertyChanged implementation that sends old value and new value of the change and raises the INotifyPropertyChanged event.

Extension Methods

	Name	Description
	ToDictionary()	Overloaded. Coverts any type to a Dictionary<TKey, TValue>, where the TKey is the member name and TValue the member's value. (Defined by HelperExtensions.)
	ToDictionary()	Overloaded. Coverts any type to a Dictionary<TKey, TValue>, where the TKey is the member name and TValue the member's value. (Defined by HelperExtensions.)
