I am trying to run multiple WCF Service hosting apps on the same Machine. I want to run multiple Applications - not multiple services in one application. var host = new ServiceHost(typeof(MyClass1), new Uri[] { new Uri("net.pipe://localhost") }); host.AddServiceEndpoint(typeof(ISomeInterface), new NetNamedPipeBinding(), "FOO"); host.Open(); I change "FOO" for every app, but still can not start multiple Services. Guess its pretty simple, but im stuck :( Regards Approaching it like this will do what you want, I believe: string relativeUriPart = GetUniquePartFromConfigOfThisApplicationInstance();

I have setup a WPF application that is single instance using a Mutex, this allows for the application to run within each user account if you are using user switching. The application sets up a WCF named pipe so that I can communicate to the single instance from another process (i.e. when the second process runs before it terminates due to the Mutex). I would like to know if anything should be done (best practices) to secure the named pipe? Also I would like to know if the named pipe messages would reach all running processes within the system or only within current user session. If the named

I have two .NET applications that talk to each other over a named pipe. Everything is great the first time through, but after the first message is sent, and the server is going to listen again, the WaitForConnection() method throws a System.IO.Exception with message Pipe is broken. Why am I getting this exception here? This is my first time working with pipes, but a similar pattern has worked for me in the past with sockets. Code ahoy! Server: using System.IO.Pipes; static void main() { var pipe = new NamedPipeServerStream("pipename", PipeDirection.In); while (true) { pipe.Listen(); string str

I'm looking for a good sample where NamedPipeServerStream and NamedPipeServerClient can send messages to each other (when PipeDirection = PipeDirection.InOut for both). For now I found only this msdn article . But it describes only server. Does anybody know how client connecting to this server should look like? What happens is the server sits waiting for a connection, when it has one it sends a string "Waiting" as a simple handshake, the client then reads this and tests it then sends back a string of "Test Message" (in my app it's actually the command line args). Remember that the

according to this article , WCF with named pipes is the best choice for IPC, and it is around 25 % faster than .Net Remoting. I have the following code that compares WCF with named pipes with .Net Remoting: [ServiceContract] internal interface IRemote { [OperationContract] string Hello(string name); } [ServiceBehavior] internal class Remote : MarshalByRefObject, IRemote { public string Hello(string name) { return string.Format("Hello, {0}!", name); } } class Program { private const int Iterations = 5000; static void Main(string[] args) { TestWcf(Iterations); TestRemoting(Iterations); TestWcf

I am trying to read from a named pipe (FIFO) with Fortran. Reading the data works, but the Fortran program does not seem to notice when the pipe is closed on the other end; reads simply block rather than getting an EOF. Sample program: program kitten character(256) :: buf open(22, file='test') do read(22, *) buf print*, trim(buf) end do end program kitten Now with $ mkfifo test $ echo -e '1\n2\n3' >test & $ ./kitten the program prints 1\n2\n3\n as expected, but then simply hangs. Instead, the program returns an error on EOF if test is a regular file; or you change kitten to read from STDIN and

Just started learning/using pipes and was wondering how to route file output of an application into a pipe so that another application can use it. To be exact, I want to pipe ffmpeg's output (transcoded video data) into my application to use it. If I create a named pipe like /tmp/out.mp4 and give it to ffmpeg as output filename, ffmpeg is going to try to create this file again, probably overwriting my pipe (Or something like that). How to deal with this kind of situation? is there any general way to divert File IO of an application transparently? (I am trying to write a video streaming server
