using construct with CreateFileAsync(C#)

Question

So I'm trying to output some data to a csv file. I've got no issues with the code the first time it runs but it breaks if I don't close and reopen the program (because the file is still in use.) I'm creating it with the following code.

StorageFolder folder = await StorageFolder.GetFolderFromPathAsync(Path.GetDirectoryName(folderPath));
StorageFile file = await folder.CreateFileAsync(outputFile, CreationCollisionOption.ReplaceExisting);
await FileIO.WriteTextAsync(file , content);

It was suggested I should be using the using construct but when I try it I get this error.

CS1674 'StorageFile': type used in a using statement must be implicitly convertible to 'System.IDisposable'.

There's obviously something I'm ignorant of but I don't know what.

Any help would be much appreciated.

Your class must implement IDisposable Interface
