We use BigIP to load balance between our two IIS servers. We recently deployed a WCF service hosted on by IIS 6 onto these two Windows Server 2003R2 servers. Each server is configured with two host headers: one for the load balancer address, and then a second host header that points only to that server. That way we can reference a sp...
We're deploying some new WCF calls in our SQL 2005 DB using the CLR. In testing, I hardcoded in the code the endpoint to connect to, and deployed it to our test server. When we go to deploy this to production, we will be deploying it to many different SQL DBs, and using different endpoints to connect to (same service running on different...

Within an n-tier app that makes use of a WCF service to interact with the database, what is the best practice way of making use of LinqToSql classes throughout the app?

So I am working on a project that uses a ASP.NET server and we have entities being passed over WCF from LINQ-to-Entity queries. I have already overcome the cyclic reference issue with WCF. Now that I am looking toward the next step, the Flex UI, I am wondering what things people have already faced either with dealing with WCF from Flex o...
We have an existing WCF service that makes use of wsDualHttpBinding to enable callbacks to the client. I am considering moving it to netTcpBinding for better performance, but I'm quite wary of moving away from the IIS-hosted service (a "comfort zone" we currently enjoy) into having our own Windows service to host it. I was hoping we coul...
I want to create a new net.tcp://localhost:x/Service endpoint for a WCF service call, with a dynamically assigned new open tcp port. I know that TcpClient will assign a new client side port when I open a connection to a given server. Is there a simple way to find the next open TCP port in .Net? I need the actual number, so that I can ...

If something goes wrong in a WCF REST call, such as the requested resource is not found, how can I play with the HTTP response code (setting it to something like HTTP 404, for example) in my OperationContract method? ...

I am trying to call a WCF webservice (which I developed) from a Silverlight application. For some reason the Silverlight app does not make the http soap call to the service. I know this because I am sniffing all http traffic with Fiddler (and it is not a localhost call). This my configuration in the server relevant to WCF: <system.serv...
