WCF / ASMX :: Can A WCF Service Listen To TCP Port
Aug 24, 2010
I have to develop a WCF Service which should listen to a particular TCP port for data coming in from clients. Is there a way wherein the client need not call any WCF Service methods, instead client can directly write data to that port and WCF listens to TCP port for data.

I have just noticed that a WCF service referenced as https in the web address is showing that the client is connecting on port 80

The way I quickly test the asmx file is to "View in Browser" from Visual Studio (I'm using 2005, and have IIS 6). The address shows up like this:
"http://localhost:1399/MyWebService.asmx"
where 1399 is a generated random number and can change each time I test by this process.
The books I've been reading (as well as other sources in the internet) keep referring to testing web services by typing something like this in the browser:
"http://localhost/MyFolder/MyWebService.asmx"
where "MyWebService" is the name of the web service and "MyFolder" is where that webservice is.
This "http://localhost/" with no port number testing never worked for me. Some books mention random port numbers, but most do not even mention port numbers. [URL]

we have a situation where we need to host two certificates on the same server and because we can't have two different certificates on the same server running off the same port we have assigned one certificate run through another port, which is 4443.
So the URL to our web app is now....
[URL]
If I punch this into a web browser I can access it fine, however, if I create a web reference using this URL in Visual Studio (2005) it can create the web reference fine and it builds ok. But whenever I call a web method on this service instance I get a HTTP 404 page not found Exception.
Is there any properties I need to set on the web service object to get this to work? I'm confused as to why it's not working.

I have a asp.net web app and a windows service running on separate machines. How can i enable the windows service subscribe/listen to events raised by the asp.net app on the remote machine? What methods can i use?n example of events that can be raised on the asp.net app is a user uploading a file. Once the upload has completed the windows service should be notified so it can do some work. It seems that there needs to be a layer in between asp.net and windows service, possibly another windows service or WCF app? Or plain old polling through a shared database containing the state?

A customer reported that our asmx web service is continually increasing in memory (mem usage as well as private bytes). We are able to reproduce the problem in our lab with Windows 2003 Server SP2 (fully patched) on some of the machines. The customer is using Windows 2008.
We created a Hello World web service targeting the 2.0 framework built under VS2005 SP1 and a test client that continues to call it. The memory increases steadily - approximately 40K per client request. If the test app is paused, the memory remains the same. When it is closed, the memory drops. Explicit calling of GC.Collect does not drop the memory.
We have run the memory profiler on the service and the leak is all native memory. We have uninstalled/re-installed the Framework on one of the machines but no difference. To our knowledge all of the security and IIS settings are not modified. We have compared app pool, default web site and virtual directory properties to machines that have no problem and they are identical.

Is it possible to run a web service as a particular user/service account in the same way a Windows service can?I have a service account used for connecting to the DB and want to run the webservice under this account as the users using the webservice won't have DB access.The way I see to do it is to include the Impersonate option in the Web.config file, but is there any better way to do this?

My WCF Client calls my WCF Service which then calls ASMX Web Service. The problem is i have configured my wcf client and wcf service to windows credentials type but when wcf service calls asmx service the user credentials (default windowsidentity) is not passed to asmx service.
In WCF Service i am able to get user identity by using : Thread.CurrentPrincipal.Identity.Name;
WCF Service - i have disabled anonymous access and enabled windows authentication. ASMX Web Service - i have disabled anonymous access and enabled windows authentication.

I am keep getting an error that "Service Error : wbsTest failed" where wbsTest is my webservice.
The error comes up frequently enough for the user - normally reproducible within a minute or so of working with an application.
A bit of background: An user is a remote user accessing application hosted on our servers over https. He is software firewalled and his connection isn't the fastest but it is responsive enough. When errors do not present themselves, page loads are fairly quick.

I am writing a program to measure the latency(response round trip time) for a web service. I need to have this at client side.
My initial plan is to store the time at which request is sent and then calculate the difference in time when we recieve a response from the web service. Is this the correct way to measure latency of web service. This has some overhead because of storing time and all. How can this be done?
Another option is to attach a timestamp with the SOAP request. But the server should return the timestamp. This will not be possible in case of third party web services.

I was trying to go through this tutorial:
[URL]
but when I tried to add the service reference to the silverlight app, the Add Service Reference window would show me that there was a service file, but the node wouldn't expand to show the rest of the files that contain the services and what not. I got this error instead:
"An error occurred during the processing of a configuration file required to service this request. review the specific error details below and modify your configuration file appropriately."
"Parser Error Message:There is no service behavior named 'AdventureWorks_WebServer.Service1Behavior'."
"Metadata contains a reference that cannot be resolved: 'http://localhost:55579/Service1.svc'.
The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error.
If the service is defined in the current solution, try building the solution and adding the service reference again."
here's my web.config file:

I'm just getting started with WCF services and I want to ask you if you could tell me where a WCF service runs.As far as I have researched a WCF service works as a server-side application (under IIS).I believe it works a similar way to a servlet in Tomcat.
