I have an Ajax Enabled WCF service that I call from Javascript. It works fine, but often after I make unrelated changes to the website it will fail and Javascript will report an 'Undefined' error. I can easily fix it by deleting the service, removing the system.serviceModel section of the Web.config and then recreating the service. I don't have to change any of the references in the .aspx or .js files. Also, the replacement service has identical code in the .config, .cs and .svc files (I don't see any differences). This morning, I only made some cosmetic changes and the service stopped working again.
Any insight into what I am doing wrong?
