Syntax
public enum CustomAttributeOverrideActionFields
| Name | Description |
|---|---|
| Add | Adds a new copy (possibly duplicate) of the custom attribute. |
| Default | The default action, which is Fail. |
| Fail | Emits an error message. |
| Ignore | Silently ignores this custom attribute. The attribute is not copied, and no error message is emitted. |
| MergeAddProperty | Merges the existing custom attribute with the template custom attribute by adding properties and fields. If the existing custom attribute defines the same properties and fields as the template custom attribute, they are not overridden. |
| MergeReplaceProperty | Merges the existing custom attribute with the template custom attribute by adding and replacing properties and fields. If the existing custom attribute defines the same properties and fields as the template custom attribute, they are replaced by the values defined in the template custom attribute. |
