---|---|---|
Cardinality | Gets the cardinality of the exports required by the import definition. (Inherited from ImportDefinition.) | |
Constraint | Gets an expression that defines conditions that must be matched to satisfy the import described by this import definition. (Overrides ImportDefinition.Constraint.) | |
ContractName | Gets the name of the contract. (Inherited from ImportDefinition.) | |
IsPrerequisite | Gets a value that indicates whether the import definition must be satisfied before a part can start producing exported objects. (Inherited from ImportDefinition.) | |
IsRecomposable | Gets a value that indicates whether the import definition can be satisfied multiple times. (Inherited from ImportDefinition.) | |
RequiredCreationPolicy | Gets or sets a value that indicates that the importer requires a specific CreationPolicy for the exports used to satisfy this import. | |
RequiredMetadata | Gets the metadata names of the export required by the import definition. | |
RequiredTypeIdentity | Gets the expected type of the export that matches this ContractBasedImportDefinition. |
