I have implemented a WCF service that will be used at Site A with 5 computers in the LAN accessing the service. What I would like to do is have an elevated user/administrator be able to use one of the 5 machines and query an identical service at Site B (also with 5 computers) that they will need to connect to by bypassing the LAN firewa...
I've been checking out WCF Data Services today and it looks great - but so far I haven't been able to find much about security -- specifically, limiting access to the services based on the connecting account. In SQL you have some accounts that have read only access (and those are sometimes limited to a few tables) but so far in WCF Data...
Hi there, my goal is to secure the communication between MSMQ Queue Managers – I don’t want unknown clients sending messages to my MSMQ server. I have spent many hours now trying to get Transport security working for the net.msmq binding in WCF, where MSMQ is in Workgroup mode and the client and server do not have Active Directory… so ...
I am developing a WPF application that talks to a server via WCF services over the internet. After profiling the application I noticed a lot of time is being taking up by creating the appropriate WCF client proxy and making the call to the server. The code on the server is optimised and doesn't take any time to run yet I am still seein...
So I see that MVC 2 now supports [HttpPut] and [HttpDelete] as well as [HttpGet] and [HttpPost], making it possible to do a full RESTful Web service using it. I've been using the REST toolkit for WCF for a while and find it fairly powerful, but I'd be interested to find out what (if any) advantages there are using the MVC 2 approach. ...
That's my question :) ...
I am shortly starting a project, which requires messages to be held in a queue for a period of 24 hours, this is because the database can't have any updates at certain times of the month. The service also has to be hosted on windows server 2003, which means it will have to be a windows service. It is also required that the service use W...
Hiya, I'm currently working on an Silverlight 3 project, I'm using 2 machines to test it. "harbinger" is the web server running Win7 + IIS .

Hi.. I have a solution that contains three projects. A main project with my MVC app, a silverlight application and a (silverlight enabled) WCF service project. In my silverlight project i have made a Service Reference to my WCF service. And i pretty much got that working. In my WCF service i have a method that returns an Book object, ...
The following code contains a few nested async calls within some foreach loops. I know the silverlight/wcf calls are called asyncrously -but how can I ensure that my wcfPhotographers, wcfCategories and wcfCategories objects are ready before the foreach loop start? I'm sure I am going about this all the wrong way -and would appreciate an...
Hello everybody, I started developing an application in Silverlight that was dealing with downloading the HTML of a website and then parsing it. With Silverlight 4 this can be achieved easily by simply requesting elevated permissions. With Silverlight 3, however, the only way to get the HTML of a website is via a WebService call. My ini...

Hi, I'm about to develop an service for a customer. The service will be located on the intranet behind firewalls and have a database of its own. The service will be consumed by another Web-application located on the DMZ. Now, my problem is that the company has a kind of strict policy not to open any ports from DMZ into the intranet. 1...
Hi, encountered the following problems trying to work through the quagmire of settings in WCF... I created a WCF client server service using a NetTcp binding. I didn't make any changes to the security settings and when running on one machine it works very nicely. However, when I ran my client from another machine it complained that the ...
Hi I seem to have a blocking issue with WCF. Say I have two users and each have created their own instance of a class exposed on a WCF host using net.tcp with endpoint something like this "net.tcp://localhost:32000/SymHost/". The class is PerSession context and concurrency is reentrant. The class exposes two methods Alive() which retu...

All is working well, its a simple web method(external webservice) that gets executed on the server tier(necessary, otherwise clr interop error) But I've ran into the following problems : is it possible to close the proxy one way or another? Because this option is not available in...
I'm currently learning wcf for an up and coming project. The service I am creating is using MSMQ to update the database, but the database can't accept messages at certain times. The service is going to be a windows service. The one thing I am coming up against at the moment is how I can get the service to stop reading messages from the...
Hi, I want to publish some data as XML from a SQL Server database using a WCF service to a location on our content delivery network. (www.somelocation-on-cdn/myxml.xml) This data which is published as XML will have to be updated at an interval of time. I was thinking of writing a WCF service to return the data required, create a RSS r...
I need to send byte[] array using WCF services and I care about message size and performance. My question is: Does WCF convert my binary data to Base64 string internally? (I use netTcpBinding) If it does, how to prevent it? My contract looks almost as simple as IMyService { byte[] GetData() } ...
