- name
- 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 PropertyMappingConfiguration 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.
