I have made a C++ DLL. Now I am calling it in my C# Code. I have written the following code:

using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices; //For DllImport
namespace ExternCShar
class Program
[DllImport("MathFuncsDll.dll", CharSet = CharSet.Auto)]
public static extern double Add(double a, double :thumbsup:;

static void Main()

Console.WriteLine(Add(2.3, 4.5));

Now when I run this, the following error is generated:

Debug Error!

Program: ...

An application has made an attempt to load the C Runtime library without using a manifest.

This is an unsupported way to load Visual C++ DLLs. You need to modify your application to build with a manifest.

For more information, see the "Visual C++ Libraries as Shared Side-by-Side Assemblies" topic in the product documentation.

What should I do avoid this error?
