Replaces the contents of the file referred to by the specified IStorageFile object with a new data stream of the specified Uniform Resource Identifier (URI). This method lets the app download the data on-demand when the StorageFile that represents the stream is first accessed.
The data stream is accessed through the StorageFile that is returned and the data is downloaded on-demand when the StorageFile is first accessed.
Replaces the IStorageFile object that represents the specified file with a new StorageFile that provides a stream of the specified Uniform Resource Identifier (URI).

- IStorageFile
The file that the created StorageFile will provide a stream of.
The Uniform Resource Identifier (URI) of the resource used to create the StorageFile.
- thumbnail
- IRandomAccessStreamReference
The thumbnail image for the StorageFile to create.
For a high-quality thumbnail, one edge of this thumbnail should be at least 1024 pixels.
When this method completes, it returns a StorageFile object that represents the streamed file. Subsequently, this StorageFile object should be used to access file content instead of the file (type IStorageFile) that was specified to be replace.
