NamedPipes | A pattern for client/server communication via Named Pipes | Runtime Evironment library

I am using jna module to connect two processes that both perform FFMPEG commands. Send SDTOUT of FFMPEG command on the server side to NampedPipe and receive STDIN from that NampedPipe for other FFMPEG command on the Client side.

this is how I capture STDOUT and send into the pipe in server Side:

I've set up a WCF NamedPipes Server/Client pair of applications but when the Host stops and calls ServiceHost.Close() it doesn't seem to appropriately cleanup the object from which the Host was created (using an object rather than a type to instantiate the host).

The server application code is as follows:

I have an Enterprise LOB scenario, where I need to communicate between my Sideloaded UWP app and multiple console applications which are developed by third parties. Internally, these console apps will be interfacing with COM ports and hardware devices.

Can I use App Service to communicate between UWP and out-of-package Console App?

Further more, the communication must be two way and asynchronous, expected flow:

1. UWP -start-console-app-expect-no-response-> Console App (How to achieve this step without desktop-bridge?)
2. UWP <-send-data-expect-no-response- Console App
3. UWP -send-data-expect-no-response-> Console App

I have already referred the links below but according to them "Windows Application Packaging Project" is a must.

• Communication between UWP and Non UWP app

Please do suggest if there are any other alternatives too.

EDIT:

It is possible to start out-of-package Console Apps from UWP using 2 methods:

1. Create a package with a Console App which can launch any other Console app(s). Refer: https://stackoverflow.com/a/49340814/10224384
2. Launch Console App via protocol URI. Create a URI protocol to Console App: https://docs.microsoft.com/en-us/previous-versions/windows/internet-explorer/ie-developer/platform-apis/aa767914%28v%3dvs.85%29 OR https://www.meziantou.net/registering-an-application-to-a-uri-scheme-using-net.htm

However, it is not possible to communicate between the out-of-package Console App and the UWP via the App Service. Even though, the Console app has reference to Microsoft.Windows.SDK.Contracts nuget package and can access AppServiceConnection API since AppServiceConnection class has the DualApiPartitionAttribute. The connection cannot be established with the AppServiceUnavailable Error.

Hence, Now I'm trying a new solution with option 1 from above as mentioned here: https://docs.microsoft.com/answers/questions/1166/how-uwp-can-communicate-with-windows-service.html?childToView=1211#answer-1211

Fallback options that need investigation:

• WCF Http/NamedPipes
• UWP starts Console App, Console App responds by invoking a Launch by URI protocol (Of course the UWP needs to register the Protocol)

I am developing a software in matlab appdesigner that will run two functions simultaneously under parforloop. The first function has a NamedPipe object and the error is: Functionality not supported with figures created with the uifigure function for the app variable and also unable to load .Net object . What's the problem with NamedPipe object under parforloop? How can i run namedpipe communication with parallelism in matlab appdesigner? Here is my code

I decompiled a .NET Application to write my own Injection Software. A Thread Error don't want to get removed. I tried everything but it keeps telling me that something is wrong...

I am working on an inter-process communication between a .net (v4.5.2) and Javascript node.js (v8.9.0) application. I want to use Windows named pipes for this (and only named pipes). For the Javascript application, I am using the named-pipes package (v0.0.1) I am able to establish a connection between the two applications which tells me that I am not completely off base here. I would expect to see the data event being triggered in the JavaScript application whenever I am writing a string to the NamedPipeServerStream but no data is received. I can not receive any data. Here is the code for .net and the JavaScript application. Any ideas, why that the data event is not triggered?

I have a client and a NamedPipe server. The client and the server run on distinct Windows services. On the same machine the connection works perfectly. But when attempting to access the server from another machine, an exception of type UnauthorizedAccessException is thrown (access is denied). I researched several posts and included AccessRules on the server, but it did not work. The client machine user does not exist on the server machine. Is there a specific / AccessRule setting for this case? Does anyone know the solution?

I am using NamedPipes to communicate between different modules of our windows application. At one point it is possible that a read operation could take long time so we would like to add a timeout. I added the OVERLAPPED-flag like this:
