try replace environment names environment include like.
<environment include="staging,production"> <strong>hostingenvironment.environmentname staging or production</strong> </environment> according documentation:
the
includeproperty (in asp.net core 2.0) has similar behavior ofnamesattribute in asp.net core 1.0.
update: tried migrate of projects myself (from 1.1 2.0) using packages in .csproj in order reproduce error, unfortunately no luck. not sure, maybe caused precompilation.
i had compilationfailedexception cs0246 , shows lines caused problem. rz3007(0,0) looks razor somehow broken. should open new issue on github.
not sure if helps, alo try install microsoft.aspnetcore.razor.language nuget package, because seems needed if read discussion razor changes.
also try update visual studio 2017 version 15.3 if don't use now. also, make sure sdk updated version 2.0
