Subject Re: Connection issue with trunk using .net
Date Sun, 19 Sep 2010 21:50:49 GMT
Trunk (and 0.7) use Thrift's framed transport, so you should wrap your TSocket in a TFramedTransport.
On 0.6 and earlier you should have been wrapping with a TBufferedTransport for  better performance
but the framed transport is inherently buffered.
