Description

I'm trying compare two collections, which should be equivalent. But the test fails.

Complete minimal example reproducing the issue

using System.Security.Claims;
using FluentAssertions;
using Xunit;

public class Tests {

  [Fact]
  public void collections_should_be_equivalent() {

    var collection1 = new List<Claim> {
        new Claim("foo", "bar"),
        new Claim("spam", "ham"),
      };

    var collection2 = new List<Claim> {
        new Claim("foo", "bar"),
        new Claim("spam", "ham"),
      };

    collection2.Should().ContainEquivalentOf(collection1);
  }

}

I also tried collection2.Should().ContainEquivalentOf(collection1, o => o.WithTracing()); but that doesn't provide tracing info, and when debugging, it throws XunitException.

Expected behavior:

I expect the test to pass.

Actual behavior:

The test fails.

Outcome: Failed
Error Message:
Expected collection2 {foo: bar, spam: ham} to contain equivalent of {foo: bar, spam: ham}.

Versions

• Which version of Fluent Assertions are you using? 6.2.0
• Which .NET runtime and version are you targeting? .NET SDK 6.0.101, but my project targets 5.0.404

Additional Information

I don't understand why the WithTracing option doesn't work - any ideas?
