Я запускаю VS 2010 вместе с Expression Blend 4 beta. Я создал проект MVVM Light из поставляемых шаблонов, и я получаю исключение System.IO.FileLoadException при попытке просмотреть MainWindow.Xaml в окне конструктора VS 2010. Шаблон уже ссылается на System.Windows.Interactivity. Вот детали, за исключением:MVVM Light Toolkit выбрасывает System.IO.FileLoadException
System.IO.FileLoadException

System.NotSupportedException была предпринята попытка загрузить сборку из сети с которой вызвало бы сборку быть песочницу в предыдущих версиях .NET Framework. Этот выпуск .NET Framework не включает политику CAS по умолчанию, поэтому эта загрузка может быть опасной. Если эта нагрузка не предназначена для песочницы сборки, включите переключатель loadFromRemoteSources. См. http://go.microsoft.com/fwlink/?LinkId=155569 для получения дополнительной информации.
