Introduction

Avoid the method Assembly.GetEntryAssembly(), as it might not give expected results when your code runs under test from a test runner.

Use typeof(xyz).Assembly, where 'xyz' is a class in the intended Assembly.

Code that triggers a diagnostic:

using System.Reflection;
class BadExample
{
    public void BadMethod()
    {
        var assembly = Assembly.GetEntryAssembly();
    }
}

And the replacement code:

class GoodExample
{
    public void GoodMethod()
    {
        var assembly = typeof(Program).Assembly;
    }
}

This analyzer does not offer any special configuration. The general ways of suppressing diagnostics apply.
