WCF Memory Increases dramatically

I am using WCF service. The problem I have is its starts using double memory.
I am using HTTPS binding
<wsHttpBinding>
<binding name="secureHttpBinding" closeTimeout="04:01:00" openTimeout="04:01:00" receiveTimeout="04:10:00" sendTimeout="04:01:00" allowCookies="false"
bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true">
<readerQuotas maxDepth="128" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647"/>
<security mode="Transport" >
<transport clientCredentialType="None"/>
</security>
</binding>
</wsHttpBinding>
<endpoint address="https://localhost/test.svc"
binding="wsHttpBinding"
bindingConfiguration="secureHttpBinding"
contract="IWcfContract"
name="SecureBasicHttpBinding_WcfContract">
Here is the code I am using to upload
using (Stream fileStream = File.OpenRead(logsZipFullPath))
{
// Call web server
UploadFileResponse response = _webServiceHelper.UploadFile(fileStream, currentDate, ".zip", string.Empty);
fileStream.Close();
}
Here is my model
[MessageContract]
public class UploadFileRequest : IDisposable
{
[MessageBodyMember(Order = 1)]
public Stream FileByteStream;
[MessageHeader(MustUnderstand = true)]
public string FileDescription;
}
My zip file is of 80MB.
The problem I have is at the start of the service its using 26mb which is quite fine. At the first call it uses 136MB after call completes it goes down to 26mb. which is also fine. after the second call to upload it starts using 346MB
which again gets down to 26mb after service call. My question is why it is using 346MB when the file is of only 80MB? My GC and disponse has been called correctly. But, is this normal behaviour or I am missing anything?

finally found a work around for this. According to this post
wsHttpBinding is the full-blown binding, which supports a ton of WS-*
features and standards - it has lots more security features, you can
use sessionful connections, you can use reliable messaging, you can
use transactional control - just a lot more stuff, but wsHttpBinding
is also a lot *heavier" and adds a lot of overhead to your messages as
they travel across the network
I think this is the main reason why the memory usage is high. Our requirement was to use the HTTPS certificate and we are able to use this with basicHttpBinding. SO, I changed my settings like this
<basicHttpBinding>
<binding name="BasicHttpBinding_WcfContract" closeTimeout="04:01:00" openTimeout="04:01:00" receiveTimeout="04:10:00" sendTimeout="04:01:00" allowCookies="false"
bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="2147483647" maxBufferPoolSize="2147483647"
maxReceivedMessageSize="2147483647" messageEncoding="Text" textEncoding="utf-8" transferMode="Streamed" useDefaultWebProxy="true">
<readerQuotas maxDepth="128" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647"/>
<security mode="Transport"> <-- this is the main change
<transport clientCredentialType="None" proxyCredentialType="None" realm=""/>
<message clientCredentialType="UserName" algorithmSuite="Default"/>
</security>
</binding>
</basicHttpBinding>
Note: I changed security mode none to transport to support https.
Now, everything works without the issue.
Two possible things which causes memory issues.
wsHttpBinding overheads
Stream mode is not supported in wsHttpBinding

C# WCF - net.tcp cannot find endpoint

I'm getting the following error message when trying to implement net.tcp WCF in C#:
"Could not find default endpoint element that references contract 'EventInterfaceService.IEventInterface'
in the ServiceModel client configuration section. This might be because no configuration file was found for your application,
or because no endpoint element matching this contract could be found in the client element."
On my client side I have the following code:
private void Initialize(string sInterfaceUrl, string sUserParticipantName)
{
EventInterfaceCallbackSink _callbackSink;
InstanceContext _instanceContext;
EndpointAddressBuilder _endpointAddressBuilder;
_callbackSink = new EventInterfaceCallbackSink();
_instanceContext = new InstanceContext(_callbackSink);
eventInterfaceClient = new EventInterfaceClient(_instanceContext); //Exception gets thrown here
EndpointIdentity edi = EndpointIdentity.CreateUpnIdentity(sUserParticipantName);
var endpointAddress = eventInterfaceClient.Endpoint.Address;
EndpointAddressBuilder newEndpointAddress = new EndpointAddressBuilder(endpointAddress);
newEndpointAddress.Uri = new Uri(sInterfaceUrl);
newEndpointAddress.Identity = edi;
eventInterfaceClient.Endpoint.Address = newEndpointAddress.ToEndpointAddress();
}
As you can see I get the EndPointAddress as sInterfaceUrl and the UserParticipantName as sUserParticipantName.
For the app.config I have the following:
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="basicHttpBinding_Interface" closeTimeout="00:01:00"
openTimeout="00:01:00" receiveTimeout="Infinite" sendTimeout="00:01:00"

maxBytesPerRead="4096" maxNameTableCharCount="16384" />
<security mode="None">
<transport clientCredentialType="None" />
</security>
</binding>
</basicHttpBinding>
<netTcpBinding>
<binding name="NetTcpBinding_IEventInterface"/>
</netTcpBinding>
</bindings>
<client>
<endpoint address="http://localhost:8732/HTTPWCF/" binding="basicHttpBinding"

<endpoint address="net.tcp://localhost:8733/NETTCPWCF/"
binding="netTcpBinding" bindingConfiguration="NetTcpBinding_IEventInterface"
contract="EventInterfaceService.IEventInterface" name="NetTcpBinding_IEventInterface">
</endpoint>
</client>
</system.serviceModel>
When running this code in a stand-alone client (not the actual application) it works. I can't seem to find out what's wrong. Any tips would be great!
Thanks.
Edit: Is there any way configuring this purely at runtime, so I won't need the app.config? Regarding the comments below, config file may not be found or wrong one is being used.

Your comment mentioned that you are putting your app.config stuff into a class library. This won't be read. The app.config of the executing assembly gets read instead (or the web.config since this is ASP). You will need to add your relevant config info to the config file of the executing assembly (your ASP project).
Alternatively, you could use the static ConfigurationManager class to read in your specific app.config settings:

Magento API in C# - throwing content type exception

When i am trying to use the Magento Product download webservice call in my C# application.
I am getting some content type Mismatch error. Could you please help me?
Here is my code:
using (Mage_Api_Model_Server_V2_HandlerPortTypeClient proxy = new Mage_Api_Model_Server_V2_HandlerPortTypeClient())
{
string sessionId = proxy.login("stalin", "12345678");
customerCustomerEntity[] customers = proxy.customerCustomerList(sessionId, new filters());
foreach (customerCustomerEntity customer in customers)
{
Console.WriteLine(String.Format("{0}. {1} {2}", customer.customer_id, customer.firstname, customer.lastname));
}
proxy.endSession(sessionId);
}
Here is my Web config details:
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="Mage_Api_Model_Server_V2_HandlerBinding" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="9999999" maxBufferPoolSize="524288" maxReceivedMessageSize="9999999" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true">

<security mode="None">
<transport clientCredentialType="None" proxyCredentialType="None" realm=""/>
<message clientCredentialType="UserName" algorithmSuite="Default"/>
</security>
</binding>
</basicHttpBinding>
</bindings>
<client>
<endpoint address="http://<my server ip>/magento-1.7.0.2/index.php/api/v2_soap/index/" binding="basicHttpBinding" bindingConfiguration="Mage_Api_Model_Server_V2_HandlerBinding" contract="VPMagento.Mage_Api_Model_Server_V2_HandlerPortType" name="Mage_Api_Model_Server_V2_HandlerPort"/>
</client>
And the error message is:
The content type text/html of the response message does not match the content type of the binding (text/xml; charset=utf-8). If using a custom encoder, be sure that the IsContentTypeSupported method is implemented properly. The first 361 bytes of the response were: '<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Body>
<SOAP-ENV:Fault>
<faultcode>0</faultcode>
<faultstring>SOAP extension is not loaded.</faultstring>
</SOAP-ENV:Fault>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>'.
Any solution for this issue please?.
Otherwise let me know how to use the Magento API in C#.

Java WebService with .NET issue. Results different with scvutil /wrapped and not

I'm using a well known vendor's API with a WSDL link1, link2 (click wait to download):

My client binding looks like this; and am using a service reference instead of a web reference.
UltraDNS.UltraDNS1Client client = new UltraDNS.UltraDNS1Client();
client.ClientCredentials.UserName.UserName = "user";
client.ClientCredentials.UserName.Password = "pass";
var results = client.getResourceRecordsOfZone("domain.com",1);
// Throws InvalidOperationException: There was an error reflecting 'UltraWSException'.

When I use SVCUtil to generate the proxy class with the /wrap parameter I get the following error:
{"The top XML element 'result' from namespace '' references distinct types System.String and ZoneInfoData[]. Use XML attributes to specify another XML name or namespace for the element or types."}

You appear to have used "Add Web Reference". Please use "Add Service Reference" instead.
Then see Programming WCF Security.
The service is sending you a fault of some kind (UltraWSException). WCF is having trouble deserializing it, but if you turn on message tracing, you may be able to see what the error is, and fix it.

InvalidOperationException when using soap client

I've added as wsdl file using the add servece reference dialog in vs2008.
MyService serviceproxy = new MyService();
When I instantiate the service proxy, I get an InvalidOperationException with the following text (translated from german):
Could not find default endpoint
element to the contract
"ServiceName.ServiceInterface" in the
service model refers client
configuration section. This may be
because: The application configuration
file was not found or not an endpoint
in the client element item is found,
which corresponded to this contract.
Where servicename is the name I give the service when I add it in vs2008 and ServiceInterface the interface which is automatically generated for it.
EDIT
here is what's in my app.config:
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="MyServiceBinding" closeTimeout="00:01:00"
openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
useDefaultWebProxy="true">
<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
maxBytesPerRead="4096" maxNameTableCharCount="16384" />
<security mode="None">
<transport clientCredentialType="None" proxyCredentialType="None"
realm="" />
<message clientCredentialType="UserName" algorithmSuite="Default" />
</security>
</binding>
</basicHttpBinding>
</bindings>
</system.serviceModel>

You need something like this in your config:
<client>
<endpoint binding="basicHttpBinding"
bindingConfiguration="MyServiceBinding" contract="ServiceName.ServiceInterface"
name="MyServiceEndpoint">
</endpoint>
</client>
inside your tag
I just read your comment.
So Removed the address from the endpoint config.
You can choose to specify the endpoint completely in your code or just the address like this:
MyServiceClient proxy = new MyServiceClient();
proxy.Endpoint.Address = new EndpointAddress ("http://addressto your service"); //<-- address

Check your config file - web.config if you're in a ASP.NET web app or web site, app.config if it's a Winforms or console app.
There ought to be some config for your WCF service in there - anything below <system.serviceModel> would be fine. If not - add the necessary info to your config!
OK, so if you want to specify your endpoint URL in code, you need to do this when you instantiate your client proxy class - otherwise, it'll go look in config. Using this code snippet, you'll be using the http binding configuration settings from app.config, and specify the URL separately, in code:
BasicHttpBinding binding = new BasicHttpBinding("MyServiceBinding");
EndpointAddress address = new EndpointAddress(new Uri("http://localhost:8888/YourService"));
MyService serviceproxy = new MyService(binding, address);
That way, the basicHttpBinding object will read the settings from the config under the bindings with a name=MyServiceBinding.

Edit:
Sorry, my first answer was wrong. For the client you need:
ChannelFactory<Interface> factory = new ChannelFactory< YourServiceInterface >(new basicHttpBinding(), new EndpointAddress(new Uri("http://localhost:8888/YourService")));
YourServiceInterface proxy = factory.CreateChannel();
