Errata

I'm having trouble with the first program on page 22 of the book.

The program is:

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

namespace HelloWorld.Tests
{
[TestClass]
public class WhenProgramRuns
{
private string _consoleOutput;

[TestInitialize]
public void Initialize()
{
var w = new System.IO.StringWriter();
Console.SetOut(w);

Program.Main(new string[0]);

_consoleOutput = w.GetStringBuilder().ToString().Trim();
}
[TestMethod]
public void SaysHelloWorld()
{
Assert.AreEqual("Hello, World!", _consoleOutput);
}
}
}

I'm using VS 2019
Microsoft Visual Studio Community 2019
Version 16.11.11

Microsoft.NET Framework
Version 4.8.04084

There's a difference between the book and my code.
The line in the book:
Program.Main(new string[0]);

gets replaced by VS2019 with:
AutoGeneratedProgram.Main(new string[0]);

I have tried compiling with and without the "AutoGenerated" part but the
compile fails.

I get the error:

Build started...
1>------ Build started: Project: HelloWorld, Configuration: Debug Any CPU ------
1>HelloWorld -> J:\Programming\Book_C#_8.0\HelloWorld\HelloWorld\bin\Debug\netcoreapp3.1\HelloWorld.dll
2>------ Build started: Project: HelloWorld.Test, Configuration: Debug Any CPU ------
2>J:\Programming\Book_C#_8.0\HelloWorld\HelloWorld.Test\WhenProgramRuns.cs(17,34,17,38): error CS0122: 'AutoGeneratedProgram.Main(string[])' is inaccessible due to its protection level
2>Done building project "HelloWorld.Test.csproj" -- FAILED.
========== Build: 1 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

if I use the line Program.Main(new string[0]); I get the same except

error CS0122: 'Program.Main(string[])' is inaccessible due to its protection level

Can you help from this information?
What am I doing wrong ?

Thank you.

Note from the Author or Editor:
Have you done the step described on the following page, illustrated in Example 1-3? As the book goes on to explain directly after showing the example you're referring to, we need to make a change to the code under test "to make the code accessible to the test" as the book says in the final paragraph on page 23. I would expect to see the error you've described until you've made that change.
