Hi

What's the target framework that B3Next.Clients.Web targets? My guess is that it's targeting netstandard2.0 while the project you're referencing (B3Next.Clients.Interfaces) is netcoreapp2.1. You could change the Web project's target framework to netcoreapp2.1 too if that's the issue.

Hi,
Visual Studio don't allow me to set 2.1 version

Project:B3Next.Clients.Web

here is test repo:
https://github.com/luboid/test-razor-class-library.git

PS:
If I manually change TargetFramework in B3Next.Clients.Web.csproj from netstandard2.0 to netcoreapp2.1, all is gone in right direction,
but Visual Studio scaffold project with netstandard2.0

@luboid, the way you got it working by manually changing the TargetFramework in the csproj file is fine. Alternatively, there is a different type of class library project, which would target .Net Standard, and that's what you could create from the beginning.
