Tomer Gabel's annoying spot on the 'net RSS 2.0
# Monday, September 10, 2007

If you have a WCF service that returns a stream to the caller, you should be extra-careful with the source of these streams. In my case I was redirecting a file stream over a MessageContract that looks something like this:

    [MessageContract]
    public class ItemInfo
    {
...
        [MessageBodyMember]
        public Stream ItemStream;
    }

It took one of the integration tests to fail... oddly to figure out that the stream wasn't getting disposed of after the operation was completed. The solution appears to be fairly simple, add the following lines to your service wrapper (if your concrete implementation is WCF-aware you can always just stick this straight in the implementation code):

    // Make sure stream gets disposed at the end of the operation
    OperationContext.Current.OperationCompleted += delegate { item.ItemStream.Dispose(); };
