I'm doing a WCF-REST service using C#, which connects with a database in SQL Server to return several tables. Now, I need that my service returns a PDF File, which is stored at the table, in a varbinary(MAX) field. I'm doing some research but I can't found something like I need. How can I implement the service and class to return a PDF File? Thanks

1) write a method that returns a Stream (For ex, a MemoryStream holding your pdf file).
before returning from that method
2) Set application/pdf to WebOperationContext.Current.OutgoingResponse.ContentType
3) set the length to WebOperationContext.Current.OutgoingResponse.ContentLength
Then it should work.
