CppParserOptions.ParseMacros null reference using windows headers

[amerkoleci]

Hi, I'm trying to parse windows headers (d3d11.h) in this case and if I set ParseMacros to true it crashes internally with NullReferenceException.

var sdkPath = @"C:\Program Files (x86)\Windows Kits\10\Include\10.0.19041.0\um";
            var options = new CppParserOptions
            {
                ParseMacros = true,
            };
            options.SystemIncludeFolders.Add(sdkPath);
            var headerFile = "d3d11.h";
            var compilation = CppParser.ParseFile(Path.Combine(sdkPath, headerFile), options); /* Crash here */

StackTrace:

Any thought?

No idea, It requires debugging, if you can investigate.

I'd check out https://github.com/microsoft/CsWinRT

That should give you the CS API access for the windows types you're looking for
