Avoid calling System.String.Substring()

[TorstenM1979]

I'm trying to understand how to avoid calling a method like "System.String.Substring()" with ArchUnitNET.

First I have a simple library Lib with static method:

namespace Lib
{
public static class Utility
{
public static string SubString(string input, int position)
{
return input.Substring(position);
}
}
}

Second I have an example console project to show what I want exactly:

namespace Prg
{
internal class Program
{
static void Main(string[] args)
{
// this usage is fine
Console.WriteLine(Lib.Utility.SubString("Hello World", 6));

		// this usage should not be possible and should be "reported" by ArchUnit
		Console.WriteLine("Hello World".Substring(6));

		Console.ReadKey();
	}
}

}

And, I have a simple MS unit test as follows:

using ArchUnitNET.Domain;
using ArchUnitNET.Loader;
using static ArchUnitNET.Fluent.ArchRuleDefinition;

namespace LibTest
{
[TestClass]
public class PrgTest
{
private static readonly Architecture Architecture = new ArchLoader().LoadAssemblies(System.Reflection.Assembly.Load("Prg")).Build();

	[TestMethod]
	public void TestIndexOf()
	{
		var classesThatCallStringDotSubString = Classes().That().CallAny("System.String.Substring").Should().NotExist();
		var result = classesThatCallStringDotSubString.Evaluate(Architecture).ToList();

		Assert.IsTrue(result[0].Passed);
	}
}

}

I do something wrong because the test does not fail. Can anyone help? Thanks a lot.

Sorry for bad formatting, I don't know how this can happen :-(

I have little experience with this library but here to try and help

Documentation shows you should call Check(Architecture) instead of Evaluate(Architecture) perhaps that helps?
