I am reading this book; it is very well written, and the people who wrote it are obviously very smart. Unfortunately, it is chock full of technical errors. I have wasted hours trying to get the examples to work. In the hope of saving others some time, I am listing a few of the problems I found.
In addition to these, there are lots of other errors I found in my first, casual, reading, especially in the code.
In the Fundamentals chapter (2)
Page 45, step 1: add the app.config file to the Host project, NOT the DerivativesCalculatorService project (see page 53)
error: Service ‘DerivativesCalculator.DerivativesCalculatorServiceType’ has zero application (non-infrastructure) endpoints. This might be because no configuration file was found for your application, or because no service element matching the service name could be found in the configuration file, or because no endpoints were defined in the service element.
Page 56, step 4: there should not be a colon before “svcutil” (and there is not in the screenshot below)
Page 58: The class should be DerivativesCalculatorClient rather than DerivativesCalculatorProxy (since that is the class created by the tool — see listing 2.6)
Page 67 – 72: Getting the service to run under IIS 7.0 required quite a number of additional steps, at least in my configuration.
1) — Page 69, Step 3 – Must use Add Application rather than Add Virtual Directory, at least in IIS 7.0 . I wasted quite a bit of time on this one, until I found http://social.msdn.microsoft.com/forums/en-US/wcf/thread/49d9279f-2bc1-482b-8bb0-da1261736acb/ , where this exact problem with this exact same example was noted in April 2006.
error: The type ‘DerivativesCalculatorService.Calculator’, provided as the Service attribute value in the ServiceHost directive could not be found.
2) — Need to give the IIS_IUSRS permission to the DerivitivesCalculatorService directory, so IIS can use the config file
3) — Need to give the Anonamous Login user permission to the DeriviativesCalculatorService directory, so IIS will serve it to the user
4) — I had to fix the bindings to the .svc extension using
c:windowsMicrosoft.NETFrameworkv3.0Windows Communication FoundationServiceModelReg -r
It is possible that I had that problem because I enabled IIS after I had already installed VisualStudio. Or not.
5) — I had to turn on the WCF Activation with Control Panel/Programs/Turn Windows Features On/Microsoft .NET 3.0/WCF Activation for http and non-http – see http://michael-arnett.spaces.live.com/blog/cns!5AA848FF3F707F99!1093.entry?
- error: HTTP 500 – Handler svc-Integrated has a bad module “ManagedPipelineHandler” in its module list
Page 75 – in my testing, the MSFT string was NOT encrypted when I used the netTcpBinding
Page 79 – to use the WcfTestClient with this demo, run:
WcfTestClient http://localhost:8000/Derivatives/
or
WcfTestClient http://localhost:8000/Derivatives/?wsdl
