Remove C# dynamic support from JsonNode #55430

See discussion at #53195

We can always add it back in v.next, or add a "new (more modern) dynamic" if\when that comes out.

Note regarding the new-api-needs-documentation label:

This serves as a reminder for when your PR is modifying a ref *.cs file and adding/modifying public APIs, to please make sure the API implementation in the src *.cs file is documented with triple slash comments, so the PR reviewers can sign off that change.

...stem.Text.Json/src/System/Text/Json/Serialization/Converters/Collection/StackOfTConverter.cs

@@ -14,6 +15,7 @@ protected override void Add(in TElement value, ref ReadStack state)
            ((TCollection)state.Current.ReturnValue!).Push(value);
        }

+        [DynamicDependency(DynamicallyAccessedMemberTypes.PublicParameterlessConstructor, typeof(Stack<>))]


I'm not sure we should take this approach. In the PR to support all the collection types in source-gen mode, #55566, these converters are being used by the source generator. That PR modifies them such that they perform no reflection/rooting (in source-gen mode), e.g. this diff.

I believe the plan is to replace the trimming tests that use the pre-existing serializer overloads with new ones that use the source generator instead - #53437. Given this, could we disable the failing Stack test in this PR and replace it after #55566 goes in? cc @eerhardt

Agreed. I'd rather we just delete the trimming test until we have source gen support.

Do we know why this change is causing the test to fail though?

Test failure appears infrastructure-related:

Tagging @dotnet/compat for awareness of the breaking change.

Marking this as breaking since it's a break from previous preview (which is acceptable, but should be messaged). Please fill out the template here: https://github.com/dotnet/docs/issues/new?assignees=&labels=&template=dotnet-breaking-change.md&title=
