Adopting and porting to .NET Core will become a ton easier, later this year. .NET Core 2.0 will add a ton of .NET Framework APIs.

These APIs are almost entirely coming from .NET Standard 2.0. See the jump in APIs in this table[1].

We often get asked if this is going against the promise of a light-weight development platform. Answer: not really. The new APIs are not being added to a single library, but several, including new ones. We will be updating our publishing tools to make it easier publish apps w/only the libraries you need. We are also looking at going one step further, which is publishing only the IL you need (intra-assembly optimization).

I am spending the week presenting at two Microsoft conferences in Europe (Milan, Amsterdam). I heard very similar feedback on EF yesterday in Milan. I will be passing this off to the EF team.

FYI: I'm a .NET Core team member.
