Error accessing a WCF server hosted on the local IIS: "This operation is not supported for a relative URI."

Question

I get “ This operation is not supported for relative URI. ” When I access the WCF service from my web browser. The service is hosted on the local IIS, and the following configuration:

<system.serviceModel>
    <!-- change -->

  </system.serviceModel>

Answer 1

As the error is explained, you can only have an absolute URI, not a relative. try giving an absolute URI insteadlocalhost/

<baseAddressPrefixFilters>
  <add prefix="localhost/" />
</baseAddressPrefixFilters>

Answer 2

Try it,

<serviceHostingEnvironment> <baseAddressPrefixFilters>
<add prefix="http://localhost/" />
</baseAddressPrefixFilters>
</serviceHostingEnvironment>

Answer 3

, http:// , URI ( ). , :

http://localhost ( )

http://127.0.0.1

http://your-machine-name.domain.whatever

Also try specifying a port number (for example http://localhost:8080) if you are on a non-standard port.

Finally, your endpoint tag may actually require a relative path for its address (I have seen this before), therefore:

<service behaviorConfiguration="wrCoreService.Service1Behavior" name="wrCoreService.Service1">
    <endpoint address="service1.svc" binding="customBinding" bindingConfiguration="Wrabind" contract="wrCoreService.IService1" />
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>

Answer 4

baseAddressPrefixFilters does not recognize "localhost", use the fully qualified name of the machine instead.
