本文探讨了一种特殊的415错误——不支持的媒体类型，在部署Web服务到生产服务器时出现的问题。作者尝试了多种解决方法，包括卸载和重新安装ASP.NET，但未能解决问题。最终发现问题是由于另一个使用Web Service Extensions (WSE)的Web服务导致的，并详细记录了解决过程。

I have a web service that runs fine on my Windows XP. However, when I deploy to the production server, the web service returns 415 Unsupported Media Type when calling.

I have seen this error when WSE is not enabled on the client. The problem is, the web service is NOT using WSE. so I did the usual, uninstall ASP.Net, reinstalling, adding asmx extension to IIS, same error.

Now I need to fire a debugger to see what’s going on. Surprisingly, Microsoft.Web.Services3.dll is loaded even when there is no trace of it in my projects. Now I probably know what’s going on. There is another web service in a different virtual directory that uses WSE.

OK, I will isolate my web service to a new application pool. Well, that does not help. In the end I have to add WSE configuration to both my web service and my Windows client.
