Here is the code I am attempting to unit test (it seems to compile and execute fine):

using System;
namespace Test {
class Program {
static void Main(string[] args) {
Console.WriteLine("Hello World!");
}
}
}


Here is my the code for my unit test class

using System;
using Microsoft.VisualStudio.TestTools.UnitTesting;

namespace TestTest {
[TestClass]
public class UnitTest1 {
[TestMethod]
public void TestMethod1() {
}
}
}


I have a more involved program that I am having the same problem with.

Is there a package that I can install that is compatible with all the components of MS Test?
