How to live with a circular reference with AutoFixture

setup.cs

        [TestInitialize]
        public void BeforeEach()
        {
            _fixture = new Fixture();

            // client has a circular reference from AutoFixture point of view
            _fixture.Behaviors.Remove(new ThrowingRecursionBehavior());
            _fixture.Behaviors.Add(new OmitOnRecursionBehavior());
        }

Thanks for Mike

internal static class IFixtureExtensions
  {
      public static IFixture FixCircularReference(this IFixture fixture)
      {
          fixture.Behaviors.Remove(new ThrowingRecursionBehavior());
          fixture.Behaviors.Add(new OmitOnRecursionBehavior());
          return fixture;
      }
  }

Life saver, thanks Mike!

Maybe not exactly the same thing, but I got here when was searching for a circular reference problem when using Entity Framework. In my case, some entities have circular references and to eliminate the problem with them while using AutoFixture I used .Without method so it would skip those properties:

Asset[] assets = fixture.Build<Asset>()
 .With(x => x.AssetId, 45)
   .Without(x => x.Sensors)
   .Without(x => x.Device)
   .Without(x => x.Project)
 .CreateMany(15)
 .ToArray();

@Tridy different, very clever solution to the EF problem, thank you for adding it.

What sometimes also might help is to use:

_fixture = new Fixture();
// client has a circular reference from AutoFixture point of view
_fixture.OmitAutoProperties = true;

P.S.: In case of some properties causing the problem, especially if they may not be needed to initialize the object.
