VS 2019 Warning C26812

[rchalamala]

The enum type 'boost::system::errc::errc_t' is unscoped. Prefer 'enum class' over 'enum' (Enum.3).
Can the error code be converrted to enum class?

[ayush0x00]

You might be using enum EnumName {option1,option2}. With C++ 11, enum is being destined to be used as class for security reasons.
Try using enum class EnumName {option1,option2}

[pdimov]

Boost.System supports C++03, and enum class requires C++11.
