I have a WPF application. On the same machine I have a console application.From this console application i want to see if user has successfully logged in and a particular page is open in WPF application. If this is the case then i want to show a popup in WPF application.
To implement this I Thought of using WCF services. I have got 2 options. Create a seperate WCF service and run it as soon as WPF application runs and then ask the client application to communicate.
Second option is to host the WCF service inside the WPF application and run it when WPF application starts.
I am not able to decide on which way to choose. If anyone of u has implemented this kind of setup before,please share your ideas.
Because you want to see if a page is open in the WPF application, I'd suggest hosting the WCF service in the WPF application (i.e., using the ServicHost class). Then have the console application consume the service to determine the page status as per your requirement.
Also, use the NetNamedPipeBinding (http://msdn.microsoft.com/en-us/library/system.servicemodel.netnamedpipebinding.aspx).

I have created WPF app and installed in two different PC. now I want that when I click one button from app in 1st PC, then I should get desktop notification in 2nd PC.
So I don't know how it will be done. Whether I have to use WCF or not or anything else? If I've installed this app in multiple PC then how should I send notification to particular?
I've tried to use signalR but I didn't understand how to invoke windows form method.
The application will not be closed. it'll just minimized in the tray. so my idea is that we can invoke App method from using WCF and show notification.
I want this kind of notification for my app but from webservice:
You can use self hosted WCF like here:
https://msdn.microsoft.com/en-us/library/ms731758(v=vs.110).aspx
Use net tcp binding, it will not require administrative rights.
Also there is a need to maintain a list of addresses/hosts of the PCs where your app runs. Then according to some logic you have there, choose the one that should show your notification.
You can also use a central app that coordinates, it may be a web app. Then signalR can be helpful. It becomes like a standard chat app... google can find you plenty of implementations for that.
I have a desktop application in C# and i want to make that a window service. Is it possible to make that application as a windows service? Basically i want an app that shows gui when needed and upone minimizing it goes to system try, and it should also appear in services... For application just take an example that my application have a timer and multiline text field and its also interacting with database and its showing timely status from database so when i need to see it i can start GUI from system try?
Any kind of help would be highly appriciated. Thanks!
You will need to separate your applications. Windows Service and desktop. You will need to build API hooks into your Windows Service to allow communication from your desktop application and the service. I would recommend WCF for this.
In a nutshell, a Windows Service should not interact with the desktop. It will run in a separate session than the session you are logged into, even if you are logged in as the same account the service is running under.
It is not possible to show GUI in a windows service.
What you can do is:
a. Seperate client logic from server logic, the windows service will perform the server side operations and will expose a WCF API to the client , which will handle the GUI related issues.
b. Use an external tool like Service-O-Matic to control your winforms application as if it was a windows service. see:

I want to send simple data (geolocation data to be precise) from Windows Phone 7 application to a windows forms application and use it, as I'm a total beginner in this field I don't know which tools to use.
I searched about wcf services and tested this method but there's some issues: the data is sent from the phone application but isn't sent to the winforms application (guess something is missing)
If your know how to do this in a quick way, or have good tutorials I'll be thankful.
EDIT
I found this tutorial, it show how to connect directly wp7 application and desktop application without using sockets neither wcf service, I'm wondering if it is really works if the application isn't in localhost.
the like for the tutorial: wp7 tutorial
I had a similar problem and so I created a REST/JSON WCF service hosted in IIS with AppHarbor to provide the data. There's hundreds of ways to do it (Ruby/Heroku, etc..), but that particular one fits well within the Microsoft stack. I also needed to share route data and I used the WCF service to wrap the BingMaps services so that route computations are cached and shared. Considering that I had already created a local model, moving it out of my phone project into a service took less than a few hours (including the usual config hiccups, and forgetting to add the appharbor user to my bitbucket repo).
Consuming the service from WinForms (or any client) shouldn't be an issue as the service knows nothing about the client implementation.
Here's a tutorial from code project. REST WCF Service with JSON
I think you would need to implement some sort of server side solution which you could upload to on your Windows Phone and download from on your Windows Form application. This could be achieved using a WCF service which was connected to a server side database.
Another option would be to use sockets and communicate directly with your WinForms application. Check this tutorial on how to use basic sockets on WP7.
I need to find out the performance of my application.This application works as follows-
It's a WPF windows application, which requires some data to be filled by user
On clicking Submit button, it calls WCF web services
These services save these values in DB
Which tool would be the best for this scenario?
For automated load testing you probably need two things:
A database server with data in it. There is a question regarding generating test data: Creating test data in a database
You can use the UI automation framework to simulate user input in your WPF app.
Then setup your server and run as many clients as you want to see when it falls over.
There are a couple of excellent tools. Telerik has a good tool for profiling both a .NET windows application as well as a WCF service. I've also found that JetBrains has another excellent profiler. I've used Jet Brains to profile, WCF code as well as windows applications. If you're app communicates over HTTP. Fiddler could be another good
We have a requirement to start a WPF application with specific parameters from a link in a browser.
We are wondering if this is possible?
As an alternative could we embed the web application in a WPF browser control, and read the values out of the html web page?
Several possibilities :
if you control the browser (i.e. if you are in an intranet scenario, and have the opportunity to deploy applications), you can :
create an activex or plugin that runs the application
register a new uri scheme to interpret the url of kind "yourapplication://yourarguments"
(complex): deploy a listening app ran under the user session, and from the webapplication, ask this listening app to run the target application
reduce the security of the browser (not recommended)
if you don't control the browser:
create a clickonce application... this involves a setup, but which does not require admin privilege
Moving to Silverlight also might be an option, depending on your needs. SilverLigth V5 (still in beta) notably adds the ability for an admin to control the rights of the application via a GPO
Note: My feelings is the later option (Silverlight) is far more preferable because it's a lot more cleaner and less security hole factor. However, it can only be done if your requirements fits into the SL features
It is not possible to call client app from a browser, previously it was possible from activex controls but for that you need to have a signed library, in wpf you can make browser based application but you cant embed your web app in it.
So partially you are correct if you used wpf app you will be able to launch application on client side but with browser it seems difficult until unless you make activex control
but still i am not 100% sure that with activex control you will be able to launch the app or not
