input: [Category] Contracts [Description] The MetadataHelper class provided for a runtime way of parsing and querying the contracts of a running service. It allows the client to find out programmatically if the service supports a specified contract, it obtains all contracts of a running service, or the operations of a specified contract. These powerful and useful features are often required during setup or in administration applications and tools. [Last Updated] 9/7/2006 [Title]
