This was introduced by #73241, but it would seem that the errors being thrown are appropriate in this context — the constructor parameter names have been trimmed away and therefore it is not possible to bind them to a meaningful JSON contract.

I’m surprised we’re running the reflection serialization tests with trimming enabled, since that is not supported and they could fail in all sorts of ways, including this one cc @eerhardt

We are using trimming just to reduce code size for AOT, to save on build time.

Understood, but at the same time these are tests for components that are inherently incompatible with trimming. We should probably just disable the tests for trimmed applications if there is such an attribute.

Can we add something to preserve the needed bits though, so the tests can pass? We can do that just for the wasm+trimming case.

As in specifically prevent trimming of Tuple parameter names? We use ILLink.* files in product code to suppress trimming of required members, although I haven't done it for tests (and I'm not sure how one could specifically prevent trimming for parameter names). @eerhardt might know.

We use similar stuff in some test projects, like:

runtime/src/libraries/System.Runtime.Loader/tests/System.Runtime.Loader.Tests.csproj

Lines 66 to 69 in 8daeec2

<ItemGroup Condition="'$(TargetOS)' == 'Browser'">
<WasmFilesToIncludeFromPublishDir Include="$(AssemblyName).dll" />

The test should be marked with [ConditionalFact(typeof(PlatformDetection), nameof(PlatformDetection.IsNotBuiltWithAggressiveTrimming))] to disable it for runs with aggressive trimming. It is what we do in other similar places.

The test in question has been marked DynamicallyAccessedMemberTypes.PublicConstructors:

runtime/src/libraries/System.Text.Json/tests/Common/ConstructorTests/ConstructorTests.ParameterMatching.cs

Lines 501 to 503 in 44cb67e

[Fact]
[DynamicDependency(DynamicallyAccessedMemberTypes.PublicConstructors | DynamicallyAccessedMemberTypes.PublicProperties, typeof(Tuple<,,,,,,,>))]
public async Task TupleDeserialization_MoreThanSevenItems()

Perhaps the linker is being too eager when trimming parameter names in a constructor that has been explicitly opted out?

The test also depends on the Tuple with just one argument to be preserved. Check the error message - it complains about Tuple1`. It is due to Tuple chaining. You would also need to add the dynamic dependency on Tuple with one arg if you want to make the test work with trimming.

By the sound if it, it might be possible to fix by declaring the nested tuple type as a dynamic dependency as well.

Also, if you are using the DynamicDependency attribute, you should not need this:

var dont_trim_ctor = typeof(Tuple<,,,,,,>).GetConstructors();

It has same effect as the DynamicDependency attribute.
