MVVM Light change log

In V4.0.0 beta 1

General changes

Setup

Messenger

  • Fixed Issue #7521: race condition in Messenger.Default.
  • Fixed Issue #7539: Messenger support for uncast objects.

ViewModelBase

  • Added support for RaisePropertyChanged(null) and RaisePropertyChanged(string.empty). A blog post about this will follow.
  • Fixed Issue #7520: RaisePropertyChanged() fails in ReleaseBuild. This overload was removed because of the many issues, and replaced by the Set methods.
  • Added Set(...) methods. A blog post about this will follow.

RelayCommand

  • Fixed Issue #7522: used deprecated Predicate instead of Func.
  • Fixed Issue #7534: RelayCommand has security issue.

SimpleIoc

  • Implemented method IsRegistered<T>(). A blog post about this will follow.
  • Fixed issue "Contains<T>() is returning true even if no instance was already instantiated". Contains<T>() only returns true if an instance is already created. IsRegistered<T>() returns true if the class has been registered with the IOC container.
  • Fixed issue "Instances get created at registration already when registered with a key and a factory". Registering the instance does not execute the factory method yet. The method is only executed when the method GetInstance is called the first time.
  • Fixed issue "Use the correct DLLs for CommonServiceLocator". The original DLLs from http://commonservicelocator.codeplex.com are now used everywhere.

DispatcherHelper

  • The class was moved from GalaSoft.MvvmLight.Extras.dll into GalaSoft.MvvmLight.dll.
