This article, along with any associated source code and files, is licensed under The Code Project Open License (CPOL). Introduction. In this article, we will implement a basic WCF 4. We will build a Hello. World WCF service by carrying out the following steps: Create the solution and project. Create the WCF service contract interface. Implement the WCF service. Host the WCF service in IIS Express. Create a client application to consume this WCF service. Creating the Hello. World solution and project. Before we can build the WCF service, we need to create a solution for our service project. We also need a directory in which we will save all the files. Throughout this article, we will save our project source codes in the C: \SOAWith. WCFand. LINQ\Projects directory. We will have a subfolder for each solution we create, and under this solution folder, we will have one subfolder for each project. For this Hello. World solution, the final directory structure is shown in the following image: You don't need to manually create these directories with Windows Explorer; Visual Studio will create them automatically when you create the solutions and projects. Now follow these steps to create our first solution and the Hello. World project: 1. Start Visual Studio 2. Visual Studio Ultimate, Premium or Professional throughout this article). If the Open Project dialog box pops up, click on Cancel to close it. The New Project dialog window will appear. From the left- hand side of the window, expand Installed . From the middle section of the window, select Blank Solution. At the bottom of the window, type Hello. World as the Name and C: \SOAWith. WCFand. LINQ\Projects\ as the Location. Note that you should not enter Hello. World within the location because Visual Studio will automatically create a folder for a new solution. Click on the OK button to close this window and your screen should look like the following image with an empty solution. Depending on your settings, the layout may be different. But you should still have an empty solution in your Solution Explorer. If you don't see Solution Explorer, go to menu View . In Solution Explorer, right- click on the solution and select Add . You can also go to menu File . The following image shows the context menu for adding a new project. In the left- hand side of this window, select Installed . At the bottom of the window, type Hello. World. Service as the Name. Write C: \SOAWith. WCFand. LINQ\Projects\Hello. World as the Location. Again, don't add Hello. World. Service to the location, as Visual Studio will create a subfolder for this new project (Visual Studio will use the solution folder as the default base folder for all the new projects added to the solution). You may have noticed that there is already a template for WCF Service Application in Visual Studio 2. WCF templates in Visual Studio). For this very first example, we will not use this template. Instead, we will create everything by ourselves to understand the purpose of each step. This is an excellent way for you to understand and master this new technology. In the next chapter of my new book (see bottom of this article for more details), we will use this template to create the project, so we don't need to manually type a lot of code. Visual Studio also creates an empty class file called Class. Later, we will change this default name to a more meaningful one and change its namespace to our own one. Now you can click on the OK button to close this window. Once you click on the OK button, Visual Studio will create several files for you. The first file is the project file. This is an XML file under the project directory, and it is called Hello. World. Service. csproj. Three directories are created automatically under the project folder—one to hold the binary files, another to hold the object files, and a third one for the properties files of the project. The window on your screen should now look like the following image: We have now created a new solution and project. Next, we will develop and build this service. But before we go any further, we need to do two things to this project: Click on the Show All Files button on the Solution Explorer toolbar, as shown on previous image. Clicking on this button will show all files and directories in your hard disk under the project folder, even those items that are not included in the project. Make sure that you don't have the solution item selected. Otherwise you can't see the Show All Files button. Lastly, in order to develop a WCF service, we need to add a reference to the System. Service. Model assembly. In the Solution Explorer window, right- click on the Hello. World. Service project, and select Add Reference. You can also go to menu item Project . The Reference Manager dialog window will appear on your screen. Check System. Service. Model from the Assemblies\Framework tab and click on OK. Now, on Solution Explorer, if you expand the references of the Hello. World. Service project, you will see that System. Service. Model has been added. Also, note that System. Xml. Linq is added by default. We will use this later when we query a database. Creating the Hello. World. Service service contract interface. In the previous section, we created the solution and the project for the Hello. World WCF service. From this section on, we will start building the Hello. World WCF service. First, we need to create the service contract interface. In Solution Explorer, right- click on the Hello. World. Service project, and select Add . The following Add New Item - Hello. World. Service dialog window will appear on your screen. On the left- hand side of the window, select Installed . This will designate the interface as a WCF service contract interface. Add a Get. Message method to the interface. This method will take a string as the input and return another string as the result. It also has an attribute, Operation. Contract. Change the interface to public. Implementing the Hello. World. Service service contract. Now that we have defined a service contract interface, we need to implement it. For this purpose we will reuse the empty class file that Visual Studio created for us earlier, and modify this to make it the implementation class of our service. Before we modify this file, we need to rename it. In the Solution Explorer window, right- click on the file, Class. Hello. World. Service. Visual Studio is smart enough to change all the related files which are references to use this new name. You can also select the file and change its name from the Properties window. Next, follow the steps below to customize this class file. Hello. World. Service: IHello. World. Servicepublicstring Get. Message(string name). This is an ordinary C# method that returns a string. You can also right click on the interface link, and select Implement Interface to add the skeleton of this method. The final content of the file, Hello. World. Service. cs, should look like the following: using System. System. Collections. Generic. using System. Linq. using System. Text. using System. Threading. Tasks. Hello. World. Service. If there is no build error, it means that you have successfully created your first WCF service. If you see a compilation error, such as 'Service. Model' does not exist in the namespace 'System', this is because you didn't add the System. Service. Model namespace reference correctly. Revisit the previous section to add this reference, and you are all set. Next, we will host this WCF service in an environment and create a client application to consume it. Hosting the WCF service in IIS Express. Hello. World. Service is a class library. It has to be hosted in an environment so that client applications may access it. In this section, we will learn how to host it using IIS Express. Later, in the next chapter, we will discuss more hosting options for a WCF service. Creating the host application. There are several built- in host applications for WCF services within Visual Studio 2. However, in this section, we will manually create the host application so that you can have a better understanding of what a hosting application is really like under the hood. In subsequent chapters, we will learn and use the built- in hosting application. To host the library using IIS Express, we need to add a new website to the solution. Follow these steps to create this website: If you cannot find the template ASP. NET Empty Web SIte, make sure you have chosen New Web Site, not New Project in previous step. In Solution Explorer, right- click on the Solution file and select Add . The Add New Web Site dialog window should pop up. Select Visual C# . Change the website name from Web. Site. 1 to C: \SOAWith. WCFand. LINQ\Projects\Hello. World\Host. Dev. Server and click on OK. Now in Solution Explorer, you have one more item (Host. Dev. Server) within the solution. It will look like the following: Next, we need to set the website as the startup project. In Solution Explorer, right- click on the website, Host. Dev. Server, select Set as Start.
