Christoph Wille 41b3dd54df Add support for C# 15 closed hierarchies C# 15 (.NET 11 preview 5) encodes the closed modifier as System.Runtime.CompilerServices.ClosedAttribute on the implicitly abstract type plus CompilerFeatureRequired("ClosedClasses") on every constructor; the BCL does not ship the attribute yet, so assemblies declare their own copy or reference one from another assembly. The decompiler now reconstructs the modifier from this encoding, gated on a new C# 15 ClosedHierarchies setting. Exported projects state LangVersion preview because the compiler does not accept 15.0 yet. The pretty tests cover the definition side only: switch exhaustiveness over a closed hierarchy is compile-time knowledge that leaves no trace in the IL of consuming code. Compiling "#dependency" test assemblies to a temp file left them unresolvable while decompiling the main test assembly; they now land next to the main output. With its dependency resolvable, Issue3684 no longer needs the disambiguating base-class cast. The cross-assembly fixture also exposed a latent NRE in RecordDecompiler when a record's base type cannot be resolved. Assisted-by: Claude:claude-fable-5:Claude Code		2 months ago
