I was using Gzip Encoder to compress wcf message, it surprised me that sometimes the compression message size is even bigger than the original size, so I looked the code, I found within GZipMessageEncoderFactory.cs, the method "CompressBuffer" in the GZipMessageEncoderFactory class is not quite right. it was like this originally: private static ArraySegment<byte> CompressBuffer(ArraySegment... buffer, BufferManager bufferManager, int messageOffset) { .... var byteArray = new ArraySegment<byte>(bu...

Been using ReliableSessionBindingElement within WCF, I found we can not set the retry interval, as we only can set MaxRetryCount. WCF uses an internal algorithm to determine when to retransmit, based on a computed average round-trip time. The initial retry time is computed based on the measured roundtrip time of establishing the session. The retransmission algorithm doubles the delay with every attempt, for example, if we set the MaxRetryCount to 8(default), if WCF determines the initial retry time...
