Hallo Paul + Owen,

please add back support for VS2012. If you google for "visual studio 2017 code generation bug" you'll find an overwhelming number of reports that talk about severe code generation (invalid code) problems. This is due to a new optimizer (see https://devblogs.microsoft.com/cppblog/author/gratilupms/). VS2012 has the old mature compiler.

You can also take a look at the release notes of VS2017 and you'll find a lot of code generation bugs listed there too.

Regards Andreas
