.Net:a client for an IIS-hosted WCF service

This is the third and last post on the basics of WCF usage. I use SoapUI to consume the WSDL which exposes the single method we created in the first post, and hosted using IIS in the second post. None of this covers how to install SoapUI, although hopefully there is enough here to show you how to use it.


At the end of the previous post, we had access to the service wsdl via the link in blue:


Click on the link, and from the URL that comes up next, copy that to the clipboard:


Start SoapUI, and create a project as shown here. My PC is called [i7], so adjust your entries to match your setup, and then click OK:


After that, the left side panel should look something like this:


Double click [Request 1] and the main panel looks like this:


Just to see what happens, click the green play button in the TLH corner:


If you now put e.g. 101 rather than the default [?], you get…


, which is exactly what we expect and want.


.Net: simplest WCF service and client

In VS2015, I wanted to create the very simplest possible WCF service, and a client, in the form of a console app, to prove it works.

In VS, use the WCF template to create a WCF service library. As the template is a Hello World, I choose to call it HelloAcmeService (I don’t know why I’m randomly picking fictitious brands):

That creates an interface file, and a class file, which contain more than I want, so we strip those back to a minimum, and do some renaming.








…removing the stuff I don’t want, and some renaming:






After an OK build let’s make sure we can reference it from the browser, by pressing Start in VS , and then clicking on the BaseAddress hyperlink  in the app.config (or just typing it in):


Now we could plug the WSDL into SoapUI and get a richer client experience (if those words mean nothing, that can be for another tutorial). For now, we’ll just create a console app to use the service.

Stop the service running in VS, so you can go back to editing. Create a console app under the solution (please note – there is in fact a compile error later using this name for reasons I am not going into here, and I won’t redo the screenshots – please call the console app HelloServiceAClient – note the ‘A’):


That gives you this new content in the Solution Explorer:


You now need to add a Service Reference to use the service from this client. Right click on References/Add Service Reference…, and in the dialogue, click Discover:


Click OK, and Solution Explorer now looks like this:


Now in Program.cs, add the text highlighted to access the service and use the GetData() method from the service:


The last action before testing it is to right-click on HelloServiceAClient and select Set as Startup Project.


Now press the Play button in VS, and you get this exciting output:


That’s it.
