.net - How can I get WCF MSMQ to get more then 10 messages at a time? -

i've programmatically set msmq binding , throttling, though specify maxconcurrentcalls, maxconcurrentsessions , maxconcurrentinstances higher 10 don't manage process more 10 messages @ time.

here code create host:

        var host = new servicehost(typeof(mqprocessrequestserver));         var binding = new netmsmqbinding(netmsmqsecuritymode.none)         {             usesourcejournal = true,             receiveerrorhandling = receiveerrorhandling.drop,             receiveretrycount = 0,             maxretrycycles = 0,             retrycycledelay = timespan.fromminutes(1),             exactlyonce = true,             durable = true,             maxreceivedmessagesize = 4000000000,             receivetimeout = timespan.fromseconds(30)         };          var queueuri = string.format("net.msmq://localhost/private/{0}", scriptengineversion);         host.addserviceendpoint(typeof(imqprocessrequest), binding, queueuri);          // set throttling scriptengine.capacity in datamodel         var throttling = new servicethrottlingbehavior         {             maxconcurrentcalls = capacity,             maxconcurrentsessions = capacity,             maxconcurrentinstances = capacity         };         host.description.behaviors.add(throttling);          // set service timeout         var behavior = host.description.behaviors.find<servicebehaviorattribute>();         behavior.transactiontimeout = timespan.fromseconds(60).tostring(); 

here service behaviour:

[servicebehavior(concurrencymode = concurrencymode.multiple, instancecontextmode = instancecontextmode.percall, releaseserviceinstanceontransactioncomplete = false)] public class mqprocessrequestserver : imqprocessrequest, idisposable 

i've tried different values capacity, less 10 works fine, in @ configured, above 10 10.

the 10 connections you're allowed caused default on servicepointmanager.defaultconnectionlimit.

in notes section on msdn documentation on setting says:

when used in server environment (asp.net) defaultconnectionlimit defaults higher number of connections, 10.

in none server environment default 2.

to allow more connections set @ application start, when appdomain loads, defaultconnectionlimit.

servicepointmanager.defaultconnectionlimit = 100;  

above line should allow 100 connections.
