Managed C++ Class Library

[eSPiYa]

I've been using C# and Mono for almost a year for the cross-platform implementation of my projects. Now, I'm starting to migrate some of the existing C++ projects to .NET 2.0 instead of creating a wrapper for it due to performance issues. Here are the sample codes: Tests.h --Header File using namespace System; namespace TestFuncs { public ref class MyClass { public: int DoSomething(); }; } Tests.cpp --Source File #include "Tests.h" namespace TestFuncs { int MyClass::DoSomething() { return 100; } } TestCSharp --console application in C# namespace TestCSharp { class Program { static void Main(string[] args) { TestFuncs.MyClass MyTest = new TestFuncs.MyClass(); Console.WriteLine(MyTest.DoSomething().ToString()); } } } I've successfully compiled the project using MSVS 2005's C++ compiler then add it as a reference for my C# console application for testing. It is working fine in .NET but when I tried it in mono I receive an error: implement type compare for 1b error. During the investigation I found out that the error occurs at the constructor part TestFuncs.MyClass MyTest = new TestFuncs.MyClass();. How to solve this? Thanks.

See Kornél's "Code Generation" section.
