Thinking about service orientation, our team are involved on new application designs. We consist in a group of 4 developers and a manager (that knows something about programming and distributed systems). Each one, having own opinion on service design. It consists in a distributed system: a user interface (web app) accessing the services...
So I've created a series of objects that interact with a piece of hardware over a serial port. There is a thread running monitoring the serial port, and if the state of the hardware changes it updates properties in my objects. I'm using observable collections, and INotifyPropertyChanged. I've built a UI in WPF and it works great, show...
Good Day Everyone... Apparently, I'm not setting-up impersonation correctly for my WCF service. I do NOT want to set security on a method-by-method basis (in the actual code-behind). The service (at the moment) is open to be called by everyone on the intranet. So my questions are… Q: What web-config tags am I missing? Q: What do I ...
I am developing a DLL that will provide sychronized time stamps to multiple applications running on the same machine. The timestamps are altered in a thread that uses a high performance timer and a scalar to provide the appearance of moving faster than real-time. For obvious reasons I want only 1 instance of this time library, and I th...
Hi folks, what is your opinion or better off your practical experience using WCF to work with WSS instead of SP web services? I am writing some custom library for our software to store and retrieve files from WSS document libraries using sharepoint web services. I am not entirely happy with the performance of the sp web services - a b...
First off, i'm fairly new to programming, I've built a few asmx web services but I am a little lost regarding how I should set up a WCF web service. I've tried to research this over the past couple days by reading through a lot of the documentation/articles/videos on MSDN but I'm still a confused. Since my current web services are host...
I am going to have to interoperate with some WCF classes from an ASP.NET 2.0 web application. What tools exist that I can use to generate a proxy class that is compatible with classic XML Web Services? AFAIK, the WCF endpoints are using the basic HTTPS binding. Thanks, Matthew ...
I would like input on the design I currently have planned. Basically, I have some number of external instrumentation, each of which should always be running, collecting specific data. My thought was to create a service for each, always running and polling the instruments, performing logging, etc. There could be one instrument, or there ...
I have a third party COM component (they don't offer a .Net assy), that has the additional feature that it only works under x86 compile. I am trying to wrap this in a WCF service, but if I select x86, the service won't start (System.BadImageFormatException). Any workarounds for this ? Thanks Larry ...
I'm currently migrating an application from Linq-to-SQL & ASP.net Web Services (asmx) to Entity Framework and WCF. My question is, I have a bunch of POCO classes which i have xml mapping files for (for the linq to sql) I've replaced my linq to sql with an entity framework data model I've got an interface - something like IService - tha...
Hi all, I am writing a web app with asp.net, c# and jquery. Most of the time I'm writing dynamic html to the browser and using different web services to get the content needed. My call to the service: function WriteProducts(currentIndex, selectedCategoryId, callback) { var d = new Date(); MyAppServices.GetProducts(selectedCate...
I'm in the process of setting up a WCF Data Services web service and I'm trying to sort out the security configuration. Although there's quite a lot of documentation out there for configuring WCF security, a lot of it seems to be outmoded or does not apply to my scenario. Ultimately, I am planning on managing authorization of operations...
Hi all, I've got a WCF service setup which I can consume and use as intendid... but only on the same machine. I'm looking to get this working over multiple computers and I'm not fussed about the security. However when I set (client side) the security to = none, I get a InvalidOperationException: The service certificate is not prov...

But if u r originally in network B and even though if u have connected to networ...
I am aware of the Amazon.com exposed URIs ... which I need to sign up for and then on I can utilize them ....... roll-up my sleeves ..... and get some WCF Client test-drive coding. What are the other such publicly exposed end points that reflect real or almost real-time services? Any offerings specifically from Microsoft? I am bas...
I ran a security code analyst i found myself having a CA2105 warning. I looked at the grade tampering example. I didn't realize you can assign int[] to a readonly int. I thought readonly was like the C++ const and makes it illegal. The How to Fix Violations suggest i clone the object (which i don't want to do) or 'Replace the array with...
From what I read on the internets, WCF Data Services seem to be bound to data access via Entity Framework on the server. Is there a way to have NHibernate access mapped in the same way? ...
Hi iam making a Windows mobile application thats connects to an WCF service with basic httpbinding. The mobile device talks directly to the WCF service by tcp. But the performace is really slow. So i tried to switch the mobile device talking to a Webservice (ASMX) then the webservice talks to WCF service. The respone and performace is m...
Hi I have inherited a conventional three tier web app with ASP.net 2.0 for the UI, .Net web services (ASMX) in the middle tier and SQL Server 2005 for the DB. This is currently an intranet application with the only users being company employees. Currently the application uses Active Directory (AD) authentication. At the login screen, t...
From my perspective, the Data Services and their query approach is useful when querying simple object graphs from your server-side domain model. But when you want to query complex dependencies I couldn't create anything good out of it. The classic DTO approach is fine-grained and can handle everything, but the downside is that you have ...
