Need to generate document on the fly. for all the operation in application we are using WCF service.
(to generate the document we are plannign to use Syncfusion library, call is been made from ExtJs client and WCF service performs all db operation.)
Whats the possible solution for generating the document using WCF?
The WCF service is used to access the services from server in client mode, hence it’s not possible to open a Winforms application in WCF service. However you are trying the reverse action and we can’t access the remote application in server.
Please refer the below link for further clarifications.

I have a situation where I want to establish communication between WCF service and Windows service.
I want to pass messages from the Windows service to the WCF service
I want to send array list from the Windows service to the WCF service
How can I achieve this?
Edit:WCF is hosted on IIS.
if any code snippets it would very helpfull.
Thanks in advance

Yes you can, just add a reference to your wcf service in your windows service.
In Visual Studio right-click your project and choose Add Service Reference. Enter your WCF service address and choose namespace name. Visual Studio will download WSDL from you web service and create proxy for you.
Then just create proxy object and call web service methods:
YourNamespace.YourServiceClient client = new YourNamespace.YourServiceClient();
client.Open();
client.YourOperation();
client.Close();
I am new to windows azure plateform i want to ask a very basic question. I am doing a project on windows azure and due to some concurrency problems i want also my Browser GUI to be in the cloud which will call the web services which are also deployed in the cloud.
Just need to ask that is it possible that i will also put my GUI in the cloud and i have some URL which i will hit so that my GUI will appear in the users browser...
I want my architecture some what like that
Sorry for the drawing but i am in very hurry
Your web browser would be on the user's desktop, and make a HTTP request to a web application/site that is hosted in Windows Azure. For instance, an ASP.NET MVC web site that makes a service call to a WCF service, that then retrieves data from a SQL Azure database. One way to do this would be to create a single hosted service that contains:
Web Role (to host your ASP.NET site)
WCF Web Role (to host your WCF service)
SQL Azure (for your database)
I think the web GUI you mentioned would be like an agent, it will connect to the real websit and render the content for you. If this is true I would like to say in theroy it's possible, but in practice it will be very difficult, since what you want to do is a web based web browser. You might need to handle HTML, CSS and JS, etc.. But if it's just a web ui that render your data from your service that is fine. So back to your question, when you said the "browser gui", if it's a desktop application, you cannot run it on the cloud; if it's a website then yes you can and your proposal looks fine.
Hope my feedback helps.
I'm trying to find a (good) step-by-step example of creating a WCF and hosting it as a Windows Service (with installer). I'm using VS2010 and have a simple WCF with 1 function (just returns 'Hello').
Please don't Google and post; I'm looking for a resource someone has actually used. Most of the Googling I've done hasn't turned up much for what I'm trying to do.
I just want to take my WCF library, and find a way to install it as a Window Service. I've done it in 2008, but 2010 is... Different.
For future reference - for anyone else looking at this thread:
Here is the best example I've found for what this question was looking for:
CodeProject: WCF Service with Windows Service Hosting, consumed from C# App!
This link mentioned above shows how to consume the WCF service, but with a lot of other stuff to wade through:
MSDN: How to: Host a WCF Service in a Managed Windows Service!
This second link above is good for creating the WCF service, but not for consuming it:
MSDN: Hosting and Consuming WCF Services!
I rarely find MSDN articles that I like :-)
You just need to host the wcf contract class in your onstart method of service calling ServiceHost host = new ServiceHost(YourClass) and in onclose method of your service you need call host.close(). The hosting option depends on what type of clients you want to talk to if you want to talk to pure html clients using REST you need to host your service in WebServiceHost and the binding you need to use in that case is webHttpBinding.
I have followed the following example and was able to create windows service hosted wcf and im sure this what you are looking for link
I did not find any difference in creating wcf service in vs2008 and vs2010.
What type of clients do you want to talk and which protocols do you want to support. This all defines your configuration.
What I've used when I use WCF in a Windows Service is Topshelf as a Windows service framework and a modified version of this Code Project code to dynamically host, install and run WCF services.
Topshelf makes it very easy to develop and debug because it can be run as a console application. Being able to dynamically update WCF service libraries without stopping the Windows service is just cool. ;)
I am used to creating traditional WCF services and hosting them in IIS. I do this by creating a WCF Service Application within Visual Studio.
For my next project I want to leverage the functionality found in the new WCF Web API. However I am not sure what type of project I need to create to host the service.
Nearly all the examples I have read/seen show the service hosted in a ASP.NET Empty Web Application. Is this correct? Can I not host in in a WCF Application project and add the Web API references in that from NuGet?
I did try hosting in a WCF Application but soon fell over when it came to routing and the MapServiceRoute call in the Global.asax file which gets called on Application_Start.
Any help on this would be much appreciated.
For what I gathered from the samples, you can create the WCF as you have been creating, that is, a WCF Service Application in the WEB folder of Visual Studio.
I want to write windows service in wcf After searching a lot I only found were tutorials of writing webservice in wcf not windows service.
Can any one please provide a link to any tutorial which explains how to write windows service in WCF
Windows services are executables. WCF applications are, generally, web services, exposed over a URI. You can host a WCF application within a windows service, not the other way around.
To create a Windows service in C#, follow the step-by-step here. To make your Windows service WCF-enabled, if you will, create the System.ServiceModel.ServiceHost instance that will host your WCF service inside the OnStart() callback.
Good answers all of them. Just a quick note... implement your WCF service in a class library (dll) so you can then host it anywhere you like (IIS, Console App, or Windows Service).
I'd recommend starting from a console application, after your service works as expected, create a Windows Service, add a reference to you library and start the service (WCF) from there (Windows Service)
Edit: I just assumed you meant create a WCF service hosted as a Windows Service, if that's not the case please ignore my answer.
Create your WCF service as normal, create a Windows Service and then use ServiceHost to self-host the WCF service in your Windows Service. See this MSDN page for more information about self-hosting WCF services.
