IContract Interface

Represents the base interface for all contracts that are used for communication between components that are updated independently.

Namespace:  System.AddIn.Contract
Assembly:  System.AddIn.Contract (in System.AddIn.Contract.dll)

public interface class IContract

The IContract interface defines a contract that independently updated components, such as an application and an add-in, can use to communicate. Components can use IContract to communicate across process or application domain boundaries, or to communicate with other components in the same process or application domain. IContract serves a similar purpose for components created using the .NET Framework as the IUnknown interface serves for components created using COM. To determine whether an object implements a particular contract, use the QueryContract method.
