Description

Version Used: VS 15.5.2

Steps to Reproduce:

  1. Go to this line of code https://github.com/dotnet/roslyn/blob/b0bd4af8ff88e5692cff8a8251f1fe17bed879ef/src/Compilers/Core/Portable/PEWriter/UsedNamespaceOrType.cs#L61
  2. Hover base.Equals and Quick Info suggests there's one additional overload image
  3. Prompt Signature Info and it only shows one overload image

Expected Behavior: When Quick Info displays (+1 overload) then Signature Info should show exactly 2 overloads

Actual Behavior: Signature Info may show less overloads than Quick Info suggests there are.

Research direction
Investigate how Quick Info and Signature Help compute overload counts. Look at the file UsedNamespaceOrType.cs (line 61) and related IntelliSense providers to understand the discrepancy. Check if there is a mismatch in how overloads are enumerated between the two features.
