Why is this an issue?
If you’re using a Structure, it is likely because you’re interested in performance. But by failing to implement
IEquatable<T> you’re loosing performance when comparisons are made because without IEquatable<T>, boxing and
reflection are used to make comparisons.
Noncompliant code example
Structure MyStruct ' Noncompliant
Public Property Value As Integer
End Structure
Compliant solution
Structure MyStruct
Implements IEquatable(Of MyStruct)
Public Property Value As Integer
Public Overloads Function Equals(other As MyStruct) As Boolean Implements IEquatable(Of MyStruct).Equals
' ...
End Function
End Structure
