I think there are some errors in the program coding. First of all, the order number is displayed once the form is loaded. I notices that the coded downloaded from WROX website has assigned the order number to the textbox when the form loads.

I'm using Visual Studio 2008 Beta 2 and I've set the framework to 3.5 in the project properties for all the projects; Service, Service Host, and Service Client.

In the Service Client project, I've deleted the files from service reference folder and the app.config file. I then add the service reference again and the app.config file is auto generated. I noticed that the proxy code generated for the PlaceOrder method returns void and not BookOrder and there are 6 reference parameters to be passed to the PlaceOrder method. Wehereas in the book I noticed the statement,
   result = PlaceOrder(Val1);

The statement is not correct based on the proxy code generated. I therefore call the PlaceOrder method like the following:

   PlaceOrder(ref FirstName, ...);

There isn't any errors in the compilation. However, when I run the client program and click on the Place Order button, a runtime error occurs.

Can anyone point out to me how the problem could be solved?

Thank you.

Hi Everyone,

I apologize for the late reply. I have recieved these posts and will look into them immediately. I have just finished wrappign up my third book on LINQ and have been unable to get to these, but I am now able to turn my attention to these requests.

First, let me apologize for the errors. They were definately not intentional, and I will spend this week looking at the chapter 6 examples and figure out why the issue is. I will post a fix/response as soon as I have an solution.

Again, my sincerest apologies.

I am having the exact same issue. I also noticed that in the downloaded code examples that Scott has the PlaceOrder method removed. This is quite frustrating.

Scott, your response will be greatly appreciated.

Readers, that was purely unintentional and am working right now to correct this.

Scott,

I look forward to your response. I am hesitent to continue on in the book until we get your update. God speed to you!! :-)

Scott,

Any update. I would like to continue working through the book but my confidence on the future programming examples are wavering a bit.

Hi jamocle,

I truly apologize for the delay. I will be working on this over the next couple of days as I have had some other contractual items I have needed to finish. These are now complete and I will be working on the WCF items over the next couple of days.

Look for a post from me by next Monday.
