Recommended way to connect ASP.NET Core App with Dynamics 365

Dears

I have been reading (and trying myself) about the connectivity and compatibility challenges developers are having with Dynamics 365 SDK and .NET Core (or .NET Standard 2.0 and above). 

This has become a dilemma that there's no official response from the Microsoft on the roadmap of SDK support. We have been developing plugins, workflows etc. using .NET SDK (as they're built on the latest frameworks of .NET easily). However, when we're trying to consume Dynamics 365 goodness from .NET Core app, it's impossible to achieve. 

I would like to know what is the best way to connect to Dynamics 365 from ASP.NET Core App.

1. Is it through the Web API (which is so raw)
2. Or any good workaround with CRM SDK Tools

Thanks
