The ContractReferenceAssemblyAttribute type exposes the following members.

Constructors
  NameDescription
Public method Supported by Portable Class Library Supported in .NET for Windows Store apps ContractReferenceAssemblyAttributeInitializes a new instance of the ContractReferenceAssemblyAttribute class.
Top
Properties
  NameDescription
Public property TypeIdWhen implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)
Top
Methods
  NameDescription
Public method Supported by Portable Class Library Supported in .NET for Windows Store apps EqualsInfrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
Public method Supported by Portable Class Library Supported in .NET for Windows Store apps GetHashCodeReturns the hash code for this instance. (Inherited from Attribute.)
Public method Supported by Portable Class Library Supported in .NET for Windows Store apps GetTypeGets the Type of the current instance. (Inherited from Object.)
Public method IsDefaultAttributeWhen overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
Public method MatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Public method Supported by Portable Class Library Supported in .NET for Windows Store apps ToStringReturns a string that represents the current object. (Inherited from Object.)

Explicit Interface Implementations
  NameDescription
Explicit interface implemetation Private method _AttributeGetIDsOfNamesMaps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetation Private method _AttributeGetTypeInfoRetrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetation Private method _AttributeGetTypeInfoCountRetrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetation Private method _AttributeInvokeProvides access to properties and methods exposed by an object. (Inherited from Attribute.)

Remarks

A contract reference assembly is named assembly.Contracts.dll, where assembly is the name of the assembly from which the contracts were extracted. A contract reference assembly contains the publicly visible interface of an assembly and its contracts, but contains no code. Contract reference assemblies are used both by the runtime analyzer to inherit contracts across assemblies, and during static verification to discover contracts on methods and types from assemblies outside the assembly that is under analysis.
