summary

Shows how Visual Studio 2019 moves a legacy codebase to strictly conformant C++: flip the permissive- flag to catch late-parsed errors, use quick actions to convert macros to constexpr and strings to raw literals, apply make_unique to remove manual new/delete and resolve green-squiggle warnings, change enums to enum class, and replace a union with std::variant plus std::visit (auto-inserted #include fixes broken builds). IntelliSense + IntelliCode offers context-aware suggestions; the demo preserves identical program output while reducing file warnings to zero.
