I am trying to get started with WCF. I want to create a hello world web service that runs on ASP.NET development server. I am stuck trying to get the web server to read the service. When I open the website's directory listing in my browser and click on the "HelloWorldService.svc" file, I get the server error:
The type 'MyHelloWorldService.HelloWorldService', provided as the Service attribute value in the ServiceHost directive, or provided in the configuration element system.serviceModel/serviceHostingEnvironment/serviceActivations could not be found.
I have:
- created my service
- added a website to my project and added a reference to the service
- created a "HelloWorldService.svc" file with the following directive:
<%@ServiceHost Service="MyHelloWorldService.HelloWorldService"%>
This is how my service code files look:
