'PInvoke' is inaccessible due to its protection level

[ramjke]

Actual behavior

The build is successful, but Visual Studio 17 shows an error: 'PInvoke' is inaccessible due to its protection level.

Expected behavior

There should be no error.

Repro steps

1. NativeMethods.txt content:

   RegisterHotKey
   UnregisterHotKey
   GetSystemMetrics
   DwmSetWindowAttribute
   GetWindowLong
   GetWindowLongPtr
   GetWindowRect
   SetLastError
   SetWindowLongPtr
   SetWindowLong
   GetWindowRect
   SetWindowPos
   CallWindowProc
   GetDpiForWindow
   GetKeyboardLayout
   GetWindowThreadProcessId
   GetForegroundWindow
   CreateEvent
   SetEvent
   CoWaitForMultipleObjects
   SetForegroundWindow

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?

Context

• CsWin32 version: 0.2.229-beta
• Win32Metadata version (if explicitly set by project):
• Target Framework: .NET6.0
• LangVersion (if explicitly set by project): 10

Can you please attach a full repro? Your repro instructions don't include mention of two projects, but I can't imagine this failure without two projects being involved. In addition, the steps you do include look correct (e.g. you set public: true) in the json file, so the APIs should be public, making me wonder if the error you see is coming from a different project that doesn't set that value. So a full repro is necessary to investigate this.

Closing due to no response.

I'm seeing it with one project.

@gavin-williams if you can share a repro, I'm willing to take a look. But if you see my earlier reply, I'm pretty sure it'll fall into that case which can be solved.
