wcf中的maxReceivedMessageSize和Streaming

Question

I put maxReceivedMessageSize="52428800" transferMode="Streamed". Shouldn't streaming be more benevolent toward that value? Stream is stream and so let it pull little by little. And yet later on there is "The maximum message size quota for incoming messages (52428800) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element..."

I know that streamed implies that the server's RAM won't be overloaded, but how is it else different from buffered?

Answer 1

The maxReceivedMessageSize quota is a long value, so you can effectively set it to infinity (I'd be surprised if you can transfer more than 9,223,372,036,854,775,807 bytes, or about 8 exabytes - yes, I had to look up the one after peta). On streaming mode you can also set the maxBufferSize quota to limit how much data will be buffered in RAM at a given time.
