        Why is this an issue?

        Both the "+" operator and the "&" operator can be used to concatenate strings. However, there is a complicated set of rules around the actual behavior of the "+" operator, and whether you will get a concatenation operation, addition, a compiler error, or a Type mismatch error. On the other hand, the "&" operator can only perform concatenation, and is therefore preferred.

        Noncompliant code example

        Dim y As String = "Con" + "caten" + "ation"
        

        Compliant solution

        Dim y As String = "Con" & "caten" & "ation"
