Hosting a WCF Service

So i am new to WCF Services and 开发者_如何转开发I need to create a dulplex service (working on it) however I cannot figure out where/how to host it (external). Right now I am using http://aspspider.com for my hosting, which works fine, but i am having trouble geting a wcf service application working.

I found this example which i will be using to help get my service working. I tried to just upload the service to aspspider, but i get an error.

Configuration Error Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Parser Error Message: It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.

Source Error:

Line 29: ASP.NET to identify an incoming user.   
Line 30:  -->  
>>>Line 31: <authentication mode="Windows"/>  
Line 32: <!--  
Line 33: <customErrors> section enables configuration

The service works fine locally, so i just need help to get it working on aspspider (or if you have a better option).

I use Station5.net as my host and never had any issues with them.
