I am trying to use the Discovery feature in WCF using http://msdn.microsoft.com/en-us/library/dd456783(v=VS.100).aspx as a starting point. It works fine on my machine, but then I wanted to run the service on a different machine. The service was discovered properly but the hostname of the found service is always "localhost" which is of co...
The project we are working on is a classic 3 tiered architecture. tier 1 being the database server, tier 2 the application services and tier 3 the presentation tier (a web site). In the application services tier I have a project that includes an entity framework model and a WCF data services based service that exposes the entities withi...
I have a program with three WCF services and when I run them locally (i.e: Server and Clients are all on localhost) everything works. However when I test them across a network I get a TimoutException on two services but not the other. I've disabled the firewalls on all the machines involved in the test. I can both ping the server and acc...
Are there any ways to mock a WCF client proxy using Rhino mocks framework so I have access to the Channel property? I am trying to unit test Proxy.Close() method but as the proxy is constructed using the abstract base class ClientBase<T> which has the ICommunicationObject interface, my unit test is failing as the internal infrastructure ...
We have a WCF service consumed by an ASP.NET application which is not where we would like it to be with the speed. The slowness is seen at the networking level, not in the processing. So for example it takes 100 milliseconds for the processing, however it takes 600ms for transporting 27,000 bytes of data from one machine to the other (co...
I've written a WCF service as a wrapper around a C# utility we've written that uses the SysInternals psexec utility to run jobs on a remote system. psexec is invoked from C# with command-line parameters that specify the domain, user and password to use. All works fine when I invoke the C# utility from PowerShell locally. However, when ...
I'm trying to figure out how to set up my web.config (the client) to consume two different WCF web services one using the other using I have the two endpoint, I guess I need two different Binding configurations. This is my current binding node: <basicHttpBinding> <binding name="WebServiceProxyServiceSoapBinding" closeTimeout="00:...
This probably sounds like a terrible idea at first glance, but here is my scenario: I have a Windows service that exposes several WCF endpoints using Username authentication. The custom authenticator will either look up the user's credentials in a local database (password is stored as salted SHA-1), or it will make a WCF request to ano...
We want to track the time taken by a web service call between a client and the server. This time should not include the time taken by the server to process the request. The idea is that we want to see how much time of a web service call is lost due to the actual transfer trough the network. Does WCF already offer something in this direc...
Hello. I am working on a Silverlight/WCF application and of course have numerous async calls throughout the Silverlight program. I was wondering on how is the best way to handle the creation of the client classes and subscribing. Specifically, if I subscribe to an event in a method, after it returns does it fall out of scope? interna...
So I already have a working implementation of StructureMap with the WCF service (including custom instance provider, behaviors, etc.) When I try to have an object that is instantiated only once per user request, I use the InstanceScope.HttpContext and it throws because the context is null. Do anyone have a proper way of doing that? ...
How can I secure an webservice so my clients can use it on their applications without having to fear that their api keys will be used in other applications? ...
I'm self-hosting several services where I do this to register the service: host = new ServiceHost(typeof(MyService)); host.Open(); Behind the scenes, wcf instantiates my service via the default constructor. Is it possble to use the WCF Integration Facility of Castle Windsor to get WCF to call on Windsor to create the service when I a...
I get the following exception when trying to pass a DTO over WCF services. System.Xml.XmlException: The maximum read depth (32) has been exceeded because XML data being read has more levels of nesting than is allowed by the quota. This quota may be increased by changing the MaxDepth property on the XmlDictionaryReaderQuotas object used ...
Hello, at my workplace we are about to start a big project. My boss (a programmer, this is a startup) wishes to use ASMX webservices for this purpose. I do not want to start off a new program using deprecated technology and would like to show him this. I dislike WCF at this moment because it has such an extreme learning curve, but I'd ra...
I've added a WCF Service Library to a Silverlight project. But when I try calling a method on the service I get a CommunicationException complaining about accessing a service in a cross-domain way. I've tried adding both a crossdomain.xml and clientaccesspolicy.xml to the service library project, but it doesn't help. Any idea what I'm...
Can we use the public queues without the Windows domain? ...
I'm trying to get my head around the addressing of WCF services. We have a client-server setup where the server occasionally (maybe once a day) needs to push data to each client. I want to have a lightweight WCF listener service on each client hosted in an NT service to receive that data. We already have such an NT service setup hosting...
What are the new enhancements in WCF 4.0 and how easy would it be to upgrade existing WCF services to 4.0? ...
Hello! I need to use polling technique to notify clients about changes in server-side. So I tried to use DuplexHttpBinding (http://code.msdn.microsoft.com/duplexhttp). I works fine with non-secured messages, but I need to use message-level security in my project (UsernameForCertificate). Ok, I decided to add SymmetricSecurityBindingElem...
