Hi all,
I develop a wcf service which works in several pc connected with a network, i want to to make all clients connect to the server through internet, how can it be done?
thanks in advance.

Visual Studio -> File -> New Project -> Web -> ASP.NET Web application
After you create the Project, add a Web Service (WCF)
If you need some help in setting up RESTful web services using WCF the WCF-REST starter kit (http://www.asp.net/downloads/starter-kits/wcf-rest/) might help.
The WCF REST Starter Kit is a set of
.Net Framework classes and Visual
Studio features and templates that
enable users to create and access
REST-style Windows Communication
Foundation (WCF) services. These
services are based on the WCF web
programming model available in .Net
3.5 SP1. The starter kit also contains the full source code for all features,
detailed code samples, and unit tests.

I am trying add connected services to generate the proxy class and got this error.
Creating WCF Service proxy class
You can try to use dotnet-svcutil tool. The Windows Communication Foundation (WCF) dotnet-svcutil tool is a .NET tool that retrieves metadata from a web service on a network location or from a WSDL file, and generates a WCF class containing client proxy methods that access the web service operations.
Similar to the Service Model Metadata - svcutil tool for .NET Framework projects, the dotnet-svcutil is a command-line tool for generating a web service reference compatible with .NET Core and .NET Standard projects.
For more information about "WCF dotnet-svcutil tool for .NET Core", you can refer to this link.
I'm just wondering how to approach to my project.
In my application I have:
MVC4 project
DB_Project with Interfaces and Models
Repository_Project with interfaces implemantation - I'm using Ninject
Next step is mobile app(XAMARIN), and here is the question:
What kind of WCF project should I choose and why...WCF Service Application or WCF Service Library?
Should I add this project like any other or create separate one?
After choosing WCF project, how to use reference to Repository_Project - is this the right way?
I will give you some thoughts to consider.
1- Your Xamarin app must communicate with an asp.net web api / mvc exposed to the internet. I dont recommend exposing a WCF service to the internet for many reasons.
2- In the Data layer, repositories are abstractions to access your EF dbContext and not to call WCF services.
3- You only add complexity when justified. If you are willing to create WCF project for the xamarin app to communicate with, then i hardly discourage you. WCF project may be created in your case if you have some security policy that enforces 3-tiers architecture where the web api needs a middle tier to access the database. Otherwise, you dont need it.
2-tiers:
Xamarin -> web api -> SQL Server
3-tiers:
Xamarin -> web api -> wcf -> SQL Server
I am developing Silverlight application with Prism 4 and WCF RIA service.
I had searched on google to get sample explaining this, but failed to get any successful output.
I am confuse about how to use RIA service in PRISM Application.
Please suggest any link which provide sample for this.
Help me.
You can use WCF RIA and PRISM 4 to develop a Silverlight application. Each of the technologies is targeted at a different part of your application.
WCF RIA services provides you with the tools to communicate from client to server to persist your data.
PRISM4 is designed to allow you to construct modular well architected Silverlight (and WPF) applications.
I have a large LOB application built using this approach. I use PRISM4 modularity to load modules into my application. The viewmodels in each of the modules connect to WCF RIA domain service contexts to get and modify data.
I'd recommend looking at Nikhilk's Book Club sample application for the RIA side http://www.nikhilk.net/RIA-Services-MIX10-Slides-Code.aspx.
I am new to both Silverlight and WF (both 4.0 version), i was wondering if we can integrate WF4.0 with Silverlight 4.0 in such a way that, when we click on some button in sliverlight UI the workflow should be executed and the output from the final activity of the workflow is displayed in the Silverlight screen. If it can be done then please provide me with some link or any tutorial where i can learn about this and start implementing.
Thanks in advance.
In WF 4.0 you can have workflows started (or progressed) by WCF endpoints. Therefore, if you can call the WCF endpoint from your Silverlight application you should be able to do this quite easily. Lots of information on Microsoft's WF Developer Centre.
Assuming you are using Visual Studio 2010, you can get up and running with a very simple Silverlight -> WF example very quickly...
Create a new project (and new solution) from the 'WCF Workflow Service Application' template. The project will be named DeclarativeServiceLibraryX. This should give you a very simple WorkflowService definition using SequentialService that simply receives the request from a client (with a single integer argument) and sends a response (with the same value). This project is created as a web project so includes a Web.config.
Create a new Silverlight 4 application. You will be asked if you want to host the Silverlight app in the existing web project (created in step #1). Probably a good idea to say yes.
In the Silverlight application, select 'Add Service Reference...', then 'Discover/ Services in Solution'. Service1.xamlx will appear as an option, select it and click Ok.
VS will then generate a WCF service reference client. You could then add a TextBox & Button to capture some data, create the client and send the service call across the wire to the WCF Workflow Service. This Workflow Service could then be modified as necessary (or use these steps to add a WCF Workflow Service to your own web project).
One area that might be challenging is modifying the WCF service bindings to be compatible with Silverlight; perhaps create a Silverlight-compatible WCF service in your server-side project first, then create a WF WCF endpoint and look at the generated code & config to see how to put things together.
The MSDN Endpoint blog is also a useful resource for learning more about WF and WCF (especially with the new style lightweight REST-style 'WCF Web HTTP' bindings, which might be more suitable for consumption by a Silverlight client.
I am assuming that you don't want to host the workflow inside the Silverlight app itself, as WF is a full .Net framework component rather than being Silverlight compatible. I'm sure you could write your own lightweight workflow framework that runs inside Silverlight, but given workflow is generally a multi-user, server-side concern this probably wouldn't be very useful concern.
I found an example with WPF here for these samples. Hope they will help you a bit or at least give a general look at this topic.
Workflow Foundation is not included in the Silverlight 4.0 runtime and thus cannot be used within a Silverlight app. So Silx answer do not relate at all to Silverlight. And James Websters answer is the only solution to make use of WF from Silverlight.
You cant use WF with silverlight.... the only way is , You can call WCF service to access WF as explained by James Webster.
I'm attempting to create my first WCF service.
I've created the service and now I'm trying to call it from a asp.net (vb) web site and I've tried adding a web reference to it and using the scvutil.exe to consume the service.
So far neither have worked. It's not letting me declare the service in my code. If someone could point me to a good tutorial on how to consume a WCF service in an ASP.Net web site that would be great.
I've found numerous on how to use them with AJAX or silverlight or windows apps but nothing on using it in just a plain old website.
Please see Beginner's Guide to Windows Communication Foundation. It's part of the WCF Developer Center on MSDN, which is full of good resources.
The link above is broken. Some other links I've found while searching for it:
Developing Service-Oriented Applications
Windows Communication Foundation
Conceptual Overview
Getting Started Tutorial
How to: Create a Windows Communication Foundation Client
Basic WCF Programming
Just add service reference, use the service reference as using "reference1.xxxx" and then use the client code.
That's all after the initialization. It works for me. Let me know if you require any help.
