WCF metadata reference cannot be resolved

Question

I am having a problem where I cannot add a service link in Visual Studio 2010 through a URL.

I have a HOST file setup to allow http://mydomain.com locally and set up a web.config file to link to this url. However, when I go to add a link to the service at the URL, I get the following error:

Metadata contains a reference that cannot be resolved: 'http://mydomain.com/myservice.svc?wsdl'. The WSDL document contains links that could not be resolved. There was an error downloading 'http://mydomain.com/myservice.svc?xsd=xsd0'. The underlying connection was closed: An unexpected error occurred on a receive. Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. An existing connection was forcibly closed by the remote host Metadata contains a reference that cannot be resolved: 'http://mydomain.com/myservice.svc'. There was no endpoint listening at http://mydomain.com/myservice.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. The remote server returned an error: (404) Not Found. 

Other URLs work fine: http://mydomain.com/myservice.svc?wsdl and http://mydomain.com/myservice.svc

Here is my web.config file:

 <?xml version="1.0"?> <configuration> <system.web> <compilation debug="true" targetFramework="4.0" /> </system.web> <system.serviceModel> <services> <!-- Note: the service name must match the configuration name for the service implementation. --> <service name="FuncWS.Email" behaviorConfiguration="ServiceType" > <!-- Add the following endpoint. --> <endpoint address="myservice.svc" binding="webHttpBinding" contract="FuncWS.IEmail"></endpoint> <!-- Note: your service must have an http base address to add this endpoint. --> <endpoint contract="IMetadataExchange" binding="mexHttpBinding" address="mex" /> <host> <baseAddresses> <add baseAddress="http://mydomain.com"/> </baseAddresses> </host> </service> </services> <behaviors> <serviceBehaviors> <behavior name="ServiceType"> <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment --> <serviceMetadata httpGetEnabled="true"/> <!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information --> <serviceDebug includeExceptionDetailInFaults="false"/> </behavior> </serviceBehaviors> </behaviors> <serviceHostingEnvironment multipleSiteBindingsEnabled="true" /> </system.serviceModel> <system.webServer> <modules runAllManagedModulesForAllRequests="true"/> </system.webServer> </configuration> 

Answer 1

The solution to this problem is that IIS must have permissions on the C: \ Windows \ Temp folder. Without this, he will not be able to generate the necessary metadata.
