Writing a Client
Finally, we can write a client in F# to test our endpoint. Create a new F# application. Add a reference to the FSharpWCF project and the System.ServiceModel and System.Runtime.Serialization assemblies. I also add the following config (using the WCF Service Configuration Editor, or by hand). This config creates a client binding named Client that talks to the service URL as configured within Visual Studio:
<system.serviceModel>
<client>
<endpoint
address=
"http://localhost:11000/SimpleService.svc/Simple"
binding="basicHttpBinding"
contract="FSharpWCF.ISimpleService"
name="Client" />
</client>
</system.serviceModel>
For the client to talk to the service, we instantiate a ChannelFactory, create a new channel, and then send the name to the WCF service:
open System.ServiceModel
open FSharpWCF
let factory = new ChannelFactory<ISimpleService>("Client")
let channel = factory.CreateChannel()
let name = new Name()
name.FirstName <- "Scott"
name.MiddleInitial <- 'C'
name.LastName <- "Seely"
printf "%s" (channel.MyRequestReplyMessage(name))
factory.Close()
This prints the following line to the console:
Scott C Seely
