-## Remarks
- Temporary keys have different comparison semantics than permanent keys:
-
--   Temporary keys use reference equality. That is, two references to the exact same temporary <xref:System.Data.EntityKey> instance are equal but no other <xref:System.Data.EntityKey> instances are equal.
-
--   Permanent keys determine equality based on the values of the contained key properties and the <xref:System.Data.Metadata.Edm.EntitySet>. That is, you can have two separate <xref:System.Data.EntityKey> instances that are equal if their entity sets are the same and their key values are equal.
-
- In addition, temporary keys have no <xref:System.Data.Metadata.Edm.EntitySet> or key values, but regular keys do.
-
- The equivalent method for this operator is <xref:System.Data.EntityKey.Equals%28System.Data.EntityKey%29?displayProperty=nameWithType>.]]></format>
