Following from convention, I have explicit Connect/Disconnect methods on my service contract to aid in management of the proxies, but I'm a little unclear as to what the client should be doing. Here's my impression of how things work. When initiating the ...

Hi, I have two instances of a WCF service exposing NetTcpBinding endpoints in the application tier, which are consumed by the application tier (heavy traffic website). I need to load balanced these instances under a single VIP. Considering the tcpNet connection pooling, it is recommended to configure the load-balancer as sticky IP, and...

We currently have a WCF Service which is beginning to reach it's limits performance wise. We have decided to add another server which will host another instance of the WCF Service.

I have a WCF server using a netTcpBinding and a client. When I run them locally they work fine. If I put the server on a Windows Server 2008 machine and try to run it, it fails unless I change the address to localhost, but no clients can connect to it. I can run the client from the server to connect to a Windows Xp machine running th...

When i use this binding: private static System.ServiceModel.Channels.Binding BuildCustomBindingPIX_SAML() { ...
I have a net.tcp WCF service, and I would like the OS to pick the port that it should listen on. So I have set the port to 0 in my URI, and netstat confirms that the OS has picked a port in the 5000 range. How can I find the actual port that has been picked, in code, inside the service process? Some code to show what I have tried: Ty...

What are possible options to transfer a lot of data from one computer to another not in the same LAN. The amount of data is about 100Mb unzipped and 2Mb zipped? Another requirement is that when I create a server for this (with C#) Java clients should be able to consume it. Does WCF support something like this? But if Java clients won't...
Hi All, I have a wcf client. What is the best way of handling connections ? Is it to open and close every time you need to contact the service: void doSomething(){ MyService service = new MyService(); //try service.doThis(10); ... service.doThat(20); service.Close() // catch } Or should I...
