Description
While we can use GetSymbolInfo to retrieve the built-in operator used in an expression, we currently lack an API to retrieve the built-in operator used in a VB assignment statement. This results in analysis problems like the one causing #2560. Additionally, VB IDE features work inconsistently because built-in operators can't always be retrieved from the compiler APIs.
Module Program
Sub Main()
Dim x As Integer
x = x + 1
x += 1
End Sub
End Module
In the code above, if the user hovers over + in the first assignment statement, they'll see the built-in operator in the Quick Info tooltip:
However, there's no tooltip if they hover over +=.
This is in contrast to C#. In C#, because assignments are expressions, GetSymbolInfo can return the built-in operator for each case:
