WCF service calls SSIS package, w3wp.exe memory keeps climbing

My .net WCF service calls a SSIS package using the Package.Execute(); method. After I call execute, I set pkg.Dispose() and app = null; The memory usage keeps climbing, 100mb to 150mb all the way to almost 300mb. I am recycling the process now, but want to know the source of the problem. Any ideas? Update The application that calls the WCF service is on another server so there is no issue there.

WCF WebService / IIS Hosting & Configuration Issue Behind a Firewall

I have a simple WCF Web service. It's hosted on IIS under the default website in our production domain. (local address: By default this default website was setup for "All Unassigned" IP's on Port 80: however, I noticed that this caused the WCF Service to generate it's WSDL using the servers local DNS name. i.e. all the URIs in the wsdl were http://myserver.subdomain.domain.com/.../... This was no good as I need to expose this service to sites who have no knowledge of the produc

Programmatically and globally adding a custom WCF client endpoint behavior extension

I have the need to add a custom behavior extension to my WCF client endpoints. I tried doing this through configuration, but have been bitten by the often-mentioned bug where WFC configuration can't parse the type name correctly. So can I do this programatically instead? I can't modify the configuration sections at runtime because they are read-only. I know if I get ahold of an instance of a client proxy (i.e. ClientBase), I can add to its Endpoint.Behaviors an instance of my custom behavior

How do I authenticate a WCF Data Service?

I've created an ADO.Net WCF Data Service hosted in a Azure worker role. I want to pass credentials from a simple console client to the service then validate them using a QueryInterceptor. Unfortunately, the credentials don't seem to be making it over the wire. The following is a simplified version of the code I'm using, starting with the DataService on the server: using System; using System.Data.Services; using System.Linq.Expressions; using System.ServiceModel; using System.Web; namespac

C# WCF - Sending Custom BindableDictionary<string,CustomObject>() Over The Wire

EDIT Ok, I've got it, it's not serializable.........so, how do I go about serializing it? Scenario I have a custom BindableDictionary that I use to bind with a grid control for automatically updating the grid when the underlying datasource changes. I now want to extend my application to use WCF, so that when the server-side has finished updating the BindableDictionary with new values, it can pass this dictionary to the client, which in turn can perform the update on the Client GUI.

AspNetCompatibilityRequirement error when hosting a WCF service with AppFabric Endpoint in SharePoint 2010

I am trying to host a WCF service within SharePoint 2010 with an AppFabric endpoint. I am using the basicHttpRelayBinding. When I host the service with a standard endpoint using the basicHttpBinding (not a service bus endpoint), the service works fine. However, as soon as I add the endpoint using the basicHttpRelayBinding, I receive the following error in the event log and the service does not register with the service bus.

How can I stop VS2010 from lauching the wcf host when it's not needed?

I imported a vs2008 solution containing a class library with a wcf service defined in it. The solution also contains a console project which holds the hosting app for the service. The console app is set as the startup project. When I hit Debug, the console app tries to open the service host, but vs2010 also launches the generic WcfHost. This causes console app to crash. How do I stop the WcfHost from launching and competing with the console app that hosts the services too? or should I stop the

How can I stop the WCF test client from opening when I start debugging?

I realize that I can just make sure I don't have the service open in my active window when I start debugging, but that's a little annoying. It seems like there's got to be some setting in VS2010 somewhere to turn this off. For anyone who asks "why would you want to turn it off?", it's because the service is using both SOAP and ReST. I test ReST in browser or in Fiddler and test SOAP in SOAPUI, and really don't have a need for it. Thanks.

A misbehaving WCF service asynch call

Okay, I have a WCF service which is going to be acting as a way to access my SQL database. That part has become largely irrelevant to this question, since for some reason my WCF service crashes. Or, at least, it causes my client Silverlight application to crash. This is why I come here to ask you guys about it. So here's the code. Bear in mind that it is called asynchronously from my Silverlight client. When it is done, the string that is returned from this method is put on the screen for the c

UsernameToken and SSL in WCF 4 web service - but with basicHttpBinding

A few months ago I asked about UsernameToken and SSL in WCF 4 web service and received a good answer using wsHttpBinding.

I've tried switching the configuration as follows.... <bindings> <basicHttpBinding> <binding name="secureBinding"> <security mode="TransportWithMessageCredential"> <transport clientCre

Wcf How to clear the outgoing message buffers at the Server?

I've written a service using PollingDuplexHttpBinding which has a Silverllight client that consumes it. My Service basically has a given number of clients sending their data (quite often, every second, and the data is quite large, each call is around 5KB) to the service, and also listening for new data sent by other clients to the service to be routed to them, very similar to a chat room architecture. The problem I'm noticing is that when clients connect to the service over the internet, after

Can't change wcf contract's method return values

I'm building a WCF service, I have written the contract in the IService file and Implemented it in the Service file, The problem shows up when I try to change any of the return values of the methods I have declared and that's because they are being saved behind in the code in CustomersService namespace specifically in the CustomersServiceClient class which is locked and can't be accessed to change. This is the code I have in the ICustomersService file: [ServiceContract] public interface

Best way of validating WCF input

In my services all the methods except certain mandatory parameters and all the input parameters are encapsulated inside message contract. Right now, we are validating the input in each and every service method, Its like duplicating validation logic in all the service methods. Is there any way I can move all these validation to common place and more over I don't want my service method to be executed as the input is not valid. Appreciate your suggestions.

Which port numbers to use/avoid for web services (WCF + Rest?)

I'm looking to deploy a WCF services project to IIS - the services are both wsHttp and webHttp (not that it makes much difference!) in the same project at the moment. The server is already hosting MVC3 web sites on port 80, separate to the web services. In the future, the services and sites may be separated...depending on load/performance/cost etc. Are there "accepted/common" ports or port ranges to use for web services? Any ranges to really avoid (*obvious ports ignored of course - 25/80/80

WCF self hosted service with certificate authentication

I have created a self-hosted WCF RESTful service with basic http authentication that runs over https with a self-signed SSL certificate. Everything works fine. When users access the service operations via a web browser,they get a pop up asking for credentials (login/password). Now I want to do certificate authentication instead of basic, but it does not work. The client's browser(IE/chrome/firefox) never prompts for certificate selection, I always get a HTTP 403 error and when I set a breakpoin

WCF data contract serialization with custom XML attribute

Wcf Debugging has not been enabled on server

I am new to WCF architecture. When I am debugging an application, it gives me the error: "Unable to step into a server. The remote procedure could not be debugged. This usually indicates that debugging has not been enabled on server." The execution scenario is like: Line by line execution from top to bottom. When debug execution flow comes to the line that generates error, it calls a web service (having one line above service signature that is "http://liveUrl", RequestNamespace:="http://li

Wcf Monitor ThreadPool use

I wish to do some benchmarking on a busy WCF service (IIS-hosted, PerSession). Since WCF gets a new ThreadPool thread for each service call, I'd like to know if the ThreadPool's max threads count is ever reached, and if I should increase it (SetMaxThreads). The only way to get hard facts I can think of is to instrument the code with ThreadPool.GetAvailableThreads. Is there any way for me to monitor if ThreadPool has reached max threads and is waiting for threads to be released? Thanks.

WCF Self-Hosted Data Services with CORS and Basic Auth support

I'm building a WCF Self-Hosted Data Service (OData, by the way) and I'm using Basic Authentication to authenticate users.

I've tried many implementations, some documented (for instance, this), other made by myself. The problem is, if I let Basic Auth enabled, because the CORS preflight request (OPTIONS) doe

Wcf OperationContextScope vs MessageInpectors

Help me in understanding differences between these two. as per to me, Operation ContextScope can be used irrespective of .NET application you are using like WCF, Console, Web, etc, anywhere this can be used if you are calling any other service like WCF or Java based service [ it this will not work in case of ASMX service] to add headers into outgoing message. If so then why we need MessageInspectors at any client side to add headers? OperationContextScope is much simpler than MessageInspectors.
