I've overriden a Stream, and returned it from server to client,
i've been trying all kind of configuration, but i saw that no matter what, the array is always 65536 sized in the Read

public override int Read(byte[] array, int offset, int count)

tried to change all kind of configuration:

<binding name="webHttpBindingConfig" transferMode="Streamed" maxReceivedMessageSize="9999" maxBufferSize="9999" maxBufferPoolSize="9999">
          <readerQuotas maxDepth="32" maxStringContentLength="81921" maxArrayLength="163841" maxBytesPerRead="40961" maxNameTableCharCount="163841"/>
          <security mode="Transport">
            <transport clientCredentialType="None" proxyCredentialType="None" realm=""/>
          </security>
        </binding>

Is there anything that affects it?

Looks like you need to set maxReceivedMessageSize to some higher value

didn't help.. its still 65536 bytes per "Read".

i find that 400MB files take much time to download, maybe its because of the chunks?

You will have to try out some other options to download large files, I never worked this case and 400MB is really a huge thing to deal. Try WCF Chunking of data.

WCF should handle it, how can i enable chunking?
