Hi. I'm trying to publish some HL7 schemas (with quite a few ) as wcf services using the "WCF Service Publishing Wizard". The wizard seemingly runs and completes just fine, creating a service that exposes the schemas I want. But when I try to browse the newly created service, I get "Server Application Unavailable"... I looked in the ev...
I want to use a Silverlight application in a cloud on Azure. The communication between the Silverlight application and the WebRole is a WCF-Service with Basic-HTTP-Binding. My problem is, that the communication doesn't work. I think the endpoint-address is not correct, but I'm not sure. Can someone help me? ...
The kind of flexibility that Activerecord gives to our DB design, we are looking at it for our DAL and build model around it. We will be creating a WCF service on top of all this. Are there any gotchas or compat issues when using NHibernate based Castle Activerecord? Specially when it comes to the DataContractSerializer that WCF uses. Si...
Our system consists of a self-hosted (non-IIS) WCF service and an Asp.net website which hosts a Silverlight application. The application is supposed to do pretty much everything, the website is just a "shell" in this case. We have a hard time figuring out how to solve user authentication securely. To my knowledge, Silverlight can not h...
I'm trying to send a message to the WCF-WSHttp adapter with a dynamic send port from an orchestration, but BizTalk seems to always be reverting back to the HTTP Adapter. According to the docs that I've been able to find, I should just need to set the transport type from my expression shape to get BizTalk to use the WCF-WSHttp adapter, a...
I have an abstract class which I would like to be able to expose to WCF so that any subclasses will also be able to be started as a WCF service. This is what I have so far: [ServiceContract(Name = "PeopleManager", Namespace = "http://localhost:8001/People")] [ServiceBehavior(IncludeExceptionDetailInFaults = true)] [DataContract(Namespac...
I am researching Prism v2 by going thru the quickstarts.

I am looking at using MSMQ as a solution to do asynchronous execution in my upcoming project. I want to know the differences between using WCF and frameworks like MassTransit or even hand written MSMQ client to place/read task off MSMQ.

I am encountering a weird error when using linq-to-sql with ado.net data services. I have a simple silverlight application that connects to a remote database. I first added the linq-to-sql class and dragged a table onto the designer. Then I added a ADO.NET Data Service, updated the DataService reference to point to the L2S Data context. ...
Normally a WCF TCP channel will make a connect to a host then allow you to make method calls over it. I would like to have a service which makes outbound connections to the clients, but once the connection has been made then clients would be able to make method calls against my service as if it were a conventional connection. I suspect...
I've used this tool that microsoft ships with visual studio because it's quick and dirty http://msdn.microsoft.com/en-us/library/bb552364.aspx But it's kinda clunky and hard to work with.

Hi everyone, I have an interesting design problem and I was hoping you all could make some suggestions. I'm using C# and .NET 3.0 I have a very nice, extensible framework built on top of WCF that automates the setup of endpoints and the creation of contracts. The system I'm working in could be run in different ways - endpoints could b...

As part of trying to learn WCF, I am reading up on serialization. I am struggling to understand how I can control serialization in .NET 3.5. For instance, I have a simple class with a few public properties. By adding the DataContract attribute to that class, I can for instance control the namespace and the name of the class as it is seri...
In classic ASP.NET I’d persist data extracted from a web service in base class property as follows: private string m_stringData; public string _stringData { get { if (m_stringData==null) { //fetch data from my web service m_stringData = ws.FetchData() ...

Hi, I am currently using the binary formatter (Remoting) to serialize/deserialize objects for sending around my LAN. I have recently upgraded from 2.0 to .Net 3.5, has 3.5 introduced any new types to improve serialization performance? I’ve looked at the DataContractSerializer but this serializes anything to underlying xml right … which...
