how to create assembly or a DLL file using command prompt in .NET

Question

Hi All: I am trying to create a DLL for my .cpp source file using command prompt. I tired the following: cl /zi /clr /ld filename.cpp cl filename.cpp /clr /ld /o filename.cpp I created VB file and C# file, and want to call this DLL. For clear understanding, the code is as follows: #using using namespace System; __gc public class HelloWorldCPP { public: void SayHelloCPP() { Console::WriteLine("Hello world from managed C++!"); } }; ------------------------------------------------------------------------------------- Imports System Imports HelloWorldCPP Public Class HelloWorldVB Inherits HelloWorldCPP Sub SayHelloVB() Console.WriteLine("Hello world from Visual basic!") End Sub End Class ---------------------------------------------------------------------------------------- using System; class HelloWorldCS : HelloWorldVB { public void SayHelloCS() { String message = "Hello world from C#!"; Console.WriteLine(message); } public static int Main() { HelloWorldCS h = new HelloWorldCS(); h.SayHelloCPP(); h.SayHelloVB(); h.SayHelloCS(); return 0; } } Could some one help me out please?
