I need to parse C++ source code using C#.

I tried CppAst.net. It seems that it can parse header files, but not source files.

using CppAst;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace CppParserCppASTdotNet
{
    class Program
    {
        static void Main(string[] args)
        {
            string cppSourceCode = @"
#include <iostream>
using namespace std;

class HelloWorld {
public:
    void greet() {
        cout << ""Hello, World!"" << endl;
    }
};

int main() {
    HelloWorld obj;
    obj.greet();
    return 0;
}
";

            // Parse a C++ files
            var compilation = CppParser.Parse(cppSourceCode);
            // Print diagnostic messages
            foreach (var message in compilation.Diagnostics.Messages)
                Console.WriteLine(message);

            // Print All enums
            foreach (var cppEnum in compilation.Enums)
                Console.WriteLine(cppEnum);

            // Print All functions
            foreach (var cppFunction in compilation.Functions)
                Console.WriteLine(cppFunction);

            // Print All classes, structs
            foreach (var cppClass in compilation.Classes)
                Console.WriteLine(cppClass);

            // Print All typedefs
            foreach (var cppTypedef in compilation.Typedefs)
                Console.WriteLine(cppTypedef);
        }
    }
}

Ouput

How can I parse C++ source code in .NET?
