__char_260 (e.g.) is emitted in referenced projects, results in compilation failure

[AliveDevil]

Actual behavior

• Create LibA and ConsoleB
• Reference LibA in ConsoleB
• LibA imports SHFILEINFOW
• ConsoleB imports DROPDESCRIPTION
  Observe error

CS0121	Der Aufruf unterscheidet nicht eindeutig zwischen den folgenden Methoden oder Eigenschaften: "Windows.Win32.InlineArrayIndexerExtensions.SliceAtNull(System.ReadOnlySpan<char>)" und "Windows.Win32.InlineArrayIndexerExtensions.SliceAtNull(System.ReadOnlySpan<char>)"

Expected behavior

CsWin32 shouldn't emit __char_260 in dependent projects, nor create InlineArrayIndexerExtensions, if already exists.

Repro steps

1. NativeMethods.txt content:

LibA:

SHFILEINFOW

ConsoleB:

DROPDESCRIPTION

2. NativeMethods.json content (if present):

{
  "$schema": "https://aka.ms/CsWin32.schema.json",
  "public": true
}

3. Any of your own code that should be shared?
