AllBeEquivalentTo not working with Generic Lists

Description

Comparing two identical generic lists using AllBeEquivalentTo failing.

Complete minimal example reproducing the issue

     class Dto
    {
        public string Name { get; set; }
        public string Value { get; set; }
    }
        [TestMethod]
        public void TestBug()
        {
            var list1 = new List<Dto>
            {
                new Dto() {Name = "ABC", Value = "123"}
            };

            var list2 = new List<Dto>
            {
                new Dto() {Name = "ABC", Value = "123"}
            };

            list1.Should().AllBeEquivalentTo(list2);

        }

NOTE: This is fails if I do this.

list1.Should().AllBeEquivalentTo(list1);

Expected behavior:

I believe this should pass.

Actual behavior:

Fails with a message that looks like this.

Expected item[0] to be {Tdx.Puf.Conversion.Tests.Dto
   {
      Name = "ABC"
      Value = "123"
   }}, but found 

Tdx.Puf.Conversion.Tests.Dto
{
   Name = "ABC"
   Value = "123"
}.

With configuration:
- Use declared types and members
- Compare enums by value
- Include all non-private properties
- Include all non-private fields
- Match member by name (or throw)
- Try conversion of all members. 
- Try conversion of all members. 
- Be strict about the order of items in byte arrays

Additional Information

You’re using List<BlockContentItem> and List<InlineContentItem> and insert TextBlocks, and TextContentItems. Per default BeEquivalentTo will use the compile-time types, so it will only compare the properties declared on BlockContentItem and InlineContentItem.

To use the run-time types use RespectingRuntimeTypes().

That did the trick. Thanks so much for the quick reply. I’m going to close this.
