The scenario is:
A Host Service communicate directly with a client without ServiceSite in IIS.
I want to download a file from Server to a Client. If the size file is more than 60kb the host service generate this error:
{System.ServiceModel.CommunicationException: The underlying connection was closed: An unexpected error occurred on a receive. ---> System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. ---> System.IO.IOException: Unable to read data from the transport connection: Connessione in corso interrotta forzatamente dall'host remoto. ---> System.Net.Sockets.SocketException: Connessione in corso interrotta forzatamente dall'host remoto

Hi.
You may need to set your maxMessageSize.
<bindings> <basicHttpBinding> <binding name="Binding1" hostNameComparisonMode="StrongWildcard" receiveTimeout="00:10:00" sendTimeout="00:10:00" openTimeout="00:10:00" closeTimeout="00:10:00" maxMessageSize="65536" maxBufferSize="65536" maxBufferPoolSize="524288" transferMode="Buffered" messageEncoding="Text" textEncoding="utf-8" bypassProxyOnLocal="false" useDefaultWebProxy="true" > <security mode="None" /> </binding> </basicHttpBinding> </bindings>Also, please see this article moving large amounts of data:

Hi,
I resolved the problem to insert the attribute "transferMode="Streamed" " in client config file.
<basicHttpBinding>
<binding name="ServiceBinding" transferMode="Streamed" closeTimeout="01:00:00" openTimeout="01:00:00"
receiveTimeout="01:00:00" sendTimeout="01:00:00" maxReceivedMessageSize="2147483647" />
</basicHttpBinding>

//I changed your config file
changes:
//increased Max Received Message size
maxReceivedMessageSize="2147483647"
//Adding tracing info to trouble shoot this problem,by default,This will create trace in c:\,if you want change the path,you can change,once you have trace info,open this trace in svctraceviewer(http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=373460&SiteID=1)
can you please try this config,if you still see the problem,can you please send me trace files and if possible repro code also,my email id is madhup@microsoft.com
