Help with WCF

RobertPincus — Wed, 04 Jan 2012 14:47:35 GMT

I have embeded a WCF service in a VS2010 project. The service simply gets the distinct city names from a table in our Sql Server 2008 SDE database. The project runs fine when running in the VS debugger. When I publish the application to our webserver, the services fail. What do I need to do to troubleshoot this? Should I create WCF services on the webserver independent of the project?

Thanks,
Robert

You might have better luck finding answers from Silverlight forum. This seems related: http://forums.silverlight.net/t/222292.aspx/1.

Robert,
Create your WCF as separated or independent Web Site of type "WCF Service".

Deploy your WCF on your IIS server:

Configure the Web.config file properly on the WCF side (set proper array sizes and bindings)

Test the WCF with a Windows or Asp.net application (Silverlight is not good for testing or debug)

After the WCF runs properly (it does what you want it to do), reference it within your Silverlight / Esri application.

If you have not done it before, you really need my help. I can help you - walk you through. The most difficult part is the settings in the Web.Config file of the WCF and the client's Web.config as well.

In my particular case, I created a standard .NET library (dll) which does all the work. Then, I created an empty Web site of type "WCF Service" which exposes (serves) the dll (I get more .NET power this way); my WCF interfase and the "Service" itself reside inside the dll, rather than on the web site. When I update the dll, I do not need to re-deploy the web site that exposes the WCF - I just copy the dll inside the "bin" folder of the Web site. The applications just refresh or update their service instances to get the updates.

Let me know...
Hugo.

This sample might also help you with some ideas how to create a service (slightly different approach than WCF but more flexible): http://www.arcgis.com/home/item.html?id=6d28a606369c43fd9a6f929541ae7c93

Still having problems getting the WCF service working on the remote server. I have been following some tutorials, but none of them seem to work. Any thoughts?
