Change max message size in DataServiceContext

I am using DataServiceContext to get data from a wcf service which is hosting a dbml. It works fine in general but queries that return large amounts of data (e.g. binary files) create the usual WCF error:

The maximum message size quota for incoming messages (65536) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding 

The problem is I cannot find how to change the message size of the channel.

Here's the code I use to initialise the class:

var channel = new RPDataModelDataContext(DataServiceBaseAddress);
channel.Credentials = Creden开发者_运维百科tialCache.DefaultCredentials;

where RPDataModelDataContext is a client proxy class generated with the entityframework

public partial class RPDataModelDataContext : 
    global::System.Data.Services.Client.DataServiceContext
{
    // ...

Can anyone point me to the right direction?

I was having tons of problems with this one as well. There were three details I was missing.

1. You MUST specify the service name exactly. This should be the fully qualified service name. (ie. Namespace.ClassName)

2. You MUST provide the EXACT address of the endpoint. (See code below)

   <services>
       <!-- The service name below has to be the EXACT Namespace.ClassName of your WCF Data Service-->
       <service name="YourDomainNameHere.YourClassNameHere">
           <!-- The address below must be the EXACT address of your service-->
           <endpoint address ="http://localhost:19766/YourServiceName.svc" binding="webHttpBinding" bindingConfiguration="higherMessageSize" contract ="System.Data.Services.IRequestHandler">
           </endpoint>
       </service>
   </services>
   

3. The maxReceivedMessageSize and the maxBufferSize must both be specified

   <bindings>
       <webHttpBinding>
           <!-- The maxReceivedMessageSize and the maxBufferSize must both be specified as shown below-->
           <binding name="higherMessageSize" maxReceivedMessageSize ="2048000" maxBufferSize="2048000"/>
       </webHttpBinding>
   </bindings>

EDIT: This may actually be a service-side issue. You should ensure that service configuration file is set as shown at the answer with most votes. You basically need to change the MaxReceivedMessageSize value to something a little bigger than your largest expected query results size. I've had to set it as high as 2 MB without any issues.

After some research I found no way to customise the Data channel service client. So I guess that its not possible to.

One has to create a normal wcf client to interact with it.
