WSDuelHttpBinding and multiple time messing between service and client in one session

Posted By:      Posted Date: October 27, 2010    Points: 0   Category :WCF

i am very new in wcf.suppose my wcf service is hosted in real ip server.Clients will request to service through internet.

client will request to service.The service will authenticate the client.After receiving the request the service will do some processing(like database update,delete,insert) and send a lot amount of data to client.client will do some database action and send an acknowledgment to service.service will keep its in database as a record.I need to do it in a session  and in a transaction.How can i do this.

i choose WSDuelHttpBinding.i read about callback operation.but according to the above scenario i also need to callback to the service again to send acknowledgment . Please help me.it's urgent .

Client Application Services - Role service cache time out bug

Hi All, For people using Client Application Services with WPF, be aware of this bug. You can configure the "cache time out" for roles to be fetched again from the service. (In the visual studio dialog, Properties -> Services -> Advanced) This means the roles are cached on the client (in a file). If the application asks for roles again, they are not fetched again for "cache time out" time. When you set this value, it goes into your App.config, transformed into seconds. So if you choose 1 minute, the App.config has: cacheTimeout="60".   However, when using the ClientRoleProvider (for instance to do something like clientRoleProvider.GetRolesForUser("SomeUser")), this cacheTimeOut is interpreted in Minutes, not seconds! To prove my point, check ClientRoleProvider.Initialize method:   string temp = config["cacheTimeout"]; if (!string.IsNullOrEmpty(temp)) _CacheTimeout = int.Parse(temp, CultureInfo.InvariantCulture);   Later on, in ClientRoleProvider.GetRolesFromDBUser (what's in a name?), you see: _CacheExpiryDate = cd.RolesCachedDateUtc.AddMinutes(_CacheTimeout);   Testing also shows this behavior. So be aware, and always put the value in minutes in your App.Config!   Regards, Koen

Best practice for WCF service exposing multiple client-specific endpoints?


Moving forward with re-designing a web service architecture using WCF, our team has been discussing how we want to expose the endpoints. Example: I have a standard endpoint that all users could use with the proper token, but I also have some number of endpoints that will instead use certificate security. All endpoints will ultimately use the same implementation, so this is really just different ways of getting in to the system.

The certificate endpoints will have to point to a specific certificate in the store so will only work for one specific client. The thought is that our standard service could live at http://mysite.com/MyService.svc and the certificate endpoints would be something like http://mysite.com/MyService.svc/Acme. The concern here is that I'm effectively putting our client list into our WSDL, which is not desirable.

What's the best practice here? Is there a way to direct multiple clients through a single certificate endpoint and get the cert on the code side (how would we know which client we're dealing with without a sp

WCF session client service reference "State" is not updated when the server side has closed


I am using vb.net (Visual Studio 2008 with framework 3.5). I have a server that exposes several services requiring sessions. I am using wsHttpBinding for all. One of my requirements is to allow non-dot net third parties to access these services. When a client connects to a service and then some time later the server goes away, the state of the connection is still reporting "open".

Currently I have implemented a "ping" function on the server. My client calls this function every 5 to 10 seconds and if the server does shutdown, I get alerted with an exception error. This works, but I was wondering if there is a way where I don't have to call my ping function?

I don't want to use a dual connection binding and I was hoping to use the connection state variable? But, I don't know how to get it to update by itself. The client user application could just wait until it goes to invoke a service method, but I was wondering if there was another way.

Thanks in advance!!


WCF service with multiple client certificates




How can I specify multiple client certificates for my service? I have a service with nettcpbinding hosted in IIS, which  will be consumed by multiple clients. Each client will be having its own certificate. I want that service should have a list of certificates of clients which are allowed to call it, for others it should fail. 


Service behavior configuration only allows one client certificate value, how can I specify multiple client certificates. My present service web.config is

Problem to obtain client IP on web service



I'm having problems to obtain the client IP on web service. Here's my scenario:

One server with Windows 2003, hosting the web service using .Net Framework 2.0, with IP and host name ServerTransaction.
Other server with Windows 2003, hosting a web application using .Net Framework 2.0, that consuming the web service on  ServerTransaction, with IP and host name ServerApplication.
Many other computers on the local network (IPs:,,, ...) acessing the web application on ServerApplication.

On the code of the web service I've tried to use HttpContext.Current.Request.UserHostAddress or HttpContext.Current.Request.ServerVariables("REMOTE_ADDR") or HttpContext.Current.Request.ServerVariables("HTTP_X_FORWARDED_FORR"), but always I can only get the IP of ServerApplication (

Any idea or tip?

Thanks and sorry for my bad english.

Looking for a simple Service and Console Client REST sample implementing BASIC authentication


Does anyone know of a C# code sample demonstrating WCF REST services and console test client with OperationContracts (GET and POST) implementing mutiple paramaters using BASIC authentication? Also, perhaps, using Fiddler as a test client as well? I have searched high and low for something like this, but have not had any success.

Multiple services in REST Collection WCF Service?


After I create a "REST Collection WCF Service" project, it contains one service "service.svc". Can I add multiple services to this project? There must be a way to do so. Otherwise, it does not make sense to create one project for each service.


My question is how to add a new service to an existing "REST Collection WCF Service" project?


Thanks a lot.

Why does .NET Framework 4 client profile slow down boot time network creation?

I've been running a Windows XP sp3 KVM virtual machine for a long time now, and some recent update made the initial network startup go from a few seconds at boot time to around 90 seconds. Using Add/Remove program to uninstall recent updates points the finger at .NET Framework 4 client profile. With it installed, if I right click on network and ask for properties right after booting, there is a 90 second delay before the network dialog with the list of network interfaces finally appears. In addition, the network drive I have automounted at login is not accessible for the same 90 seconds. As an experiment, I tried going into the device manager and deleting the network interface, and if I reboot after that it takes 90 seconds for the new hardware wizard to appear. All these 90 second delays vanish if I remove this .NET update. The network comes up as soon as the system boots.

I will appreciate it if someone can help me to undestand how the following scenario works:   There is remoting server that is registered as WellKnownObjectMode.Singleton.
