How to: Use Svcutil.exe to Validate Compiled Service Code

You can use the ServiceModel Metadata Utility Tool (Svcutil.exe) to
detect errors in service implementations and configurations without
hosting the service.

To validate a service
Compile your service into an executable file and one or more dependent
assemblies.

Open an SDK command prompt

At the command prompt, launch the Svcutil.exe tool using the following format.

svcutil.exe /validate /serviceName:<serviceConfigName> <assemblyPath>*

You must use the /serviceName option to indicate the configuration
name of the service you want to validate.

The assemblyPath argument specifies the path to the executable file
for the service and one or more assemblies that contain the service
types to be validated. The executable assembly must have an associated
configuration file to provide the service configuration. You can use
standard command-line wildcards to provide multiple assemblies.
