Комментарии

DesignTimeResourceProviderFactoryAttribute Класс позволяет ResourceProviderFactory объект для указания типа связанного объекта DesignTimeResourceProviderFactory объекта.The DesignTimeResourceProviderFactoryAttribute class allows a ResourceProviderFactory object to specify the type of the associated DesignTimeResourceProviderFactory object. DesignTimeResourceProviderFactory Класс используется для создания поставщиков во время разработки для чтения и записи ресурсов.The DesignTimeResourceProviderFactory class is used to create design-time providers for reading and writing resources. В рамках Microsoft Visual Studio 2005Microsoft Visual Studio 2005, разработчик может использовать создать локальный ресурс команды средства меню для создания ресурсов во время разработки.Within Microsoft Visual Studio 2005Microsoft Visual Studio 2005, a developer can use the Generate Local Resource command on the Tools menu to create resources during design time.
