Fields

EntityKeyPropertyName

Public constant name used for change tracking Providing this definition allows users to use this constant instead of hard-coding the string. This helps to ensure the property name is correct and allows faster comparisons in places where we are looking for this specific string. Users can still use the case-sensitive string directly instead of the constant, it will just be slightly slower on comparison. Including the dash (-) character around the name ensures that this will not conflict with a real data property, because -EntityKey- is not a valid identifier name
