According to the documentation for svcutil
/directory: - Directory to create files in (default: current directory) (Short Form: /d)
Since the default is to use the current directory, let us change the current directory for the command.
pushd "C:\Service References\Logging\"
svcutil /t:metadata http://dev.taskservices.noelnet.com/LoggingService/LoggingService.svc
popd
If you do not need to revert back to the original directory you can just use cd "C:\Service References\Logging\"
.
Note, in order for this to work, svcutil must be called using its entire path or have its path listed in the PATH environment variable. This is what I mean by calling using its entire path:
cd "C:\Service References\Logging\"
"C:\Program Files (x86)\Microsoft SDKs\Windows\v8.0A\bin\NETFX 4.0 Tools\svcutil.exe" /t:metadata http://dev.taskservices.noelnet.com/LoggingService/LoggingService.svc
