I have tried to install Microsoft.EntityFrameworkCore 3.0.0 package in a UWP project but I got the following error:
Package Microsoft.EntityFrameworkCore 3.0.0 is not compatible with uap10.0.18362 (UAP,Version=v10.0.18362) / win10-x64. Package Microsoft.EntityFrameworkCore 3.0.0 supports: netstandard2.1 (.NETStandard,Version=v2.1)
UWP application targets 18362 version, minimal version 18362.
VS version: 16.3.0
Thanks for your help!
EF Core 3 requires .net standard 2.1, which is planned but not yet supported by UWP.
.net standard 2.0 was supported by UWP 2 months after its release.

I hope UWP will also join the party
