Sets an annotation in the model for a database column that has been configured with MapKey(String[]). The annotation value can later be used when processing the column such as when creating migrations.
public System.Data.Entity.ModelConfiguration.Configuration.ForeignKeyAssociationMappingConfiguration HasColumnAnnotation (string keyColumnName, string annotationName, object value);member this.HasColumnAnnotation : string * string * obj -> System.Data.Entity.ModelConfiguration.Configuration.ForeignKeyAssociationMappingConfigurationPublic Function HasColumnAnnotation (keyColumnName As String, annotationName As String, value As Object) As ForeignKeyAssociationMappingConfigurationParameters
- keyColumnName
- String
The name of the column that was configured with the HasKey method.
- annotationName
- String
The annotation name, which must be a valid C#/EDM identifier.
- value
- Object
The annotation value, which may be a string or some other type that can be serialized with an IMetadataAnnotationSerializer
Returns
The same ForeignKeyAssociationMappingConfiguration instance so that multiple calls can be chained.
Remarks
It will likely be necessary to register a IMetadataAnnotationSerializer if the type of the annotation value is anything other than a string. Passing a null value clears any annotation with the given name on the column that had been previously set.
