Microsoft.AspNetCore.Identity.EntityFrameworkCore 3.1.2 是否对 .NET 4.7.x 项目有效？

Question

I have a .NET console project targeting .NET Framework 4.7.2.

It uses Microsoft EntityFrameworkCore 3.1.2 and Microsoft.AspNetCore.Identity.EntityFrameworkCore 2.2.0 it fails at runtime with the following error :

System.MissingMethodException
  HResult=0x80131513
  Message=Méthode introuvable : 'Microsoft.EntityFrameworkCore.Metadata.Builders.IndexBuilder Microsoft.EntityFrameworkCore.Metadata.Builders.EntityTypeBuilder`1.HasIndex(System.Linq.Expressions.Expression`1<System.Func`2<System.__Canon,System.Object>>)'.

I would say that I should upgrade Microsoft.AspNetCore.Identity.EntityFrameworkCore to version 3.1.2 but I can't:

Could not install package 'Microsoft.AspNetCore.Identity.EntityFrameworkCore 3.1.2'. You are trying to install this package into a project that targets '.NETFramework,Version=v4.7.2', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.

What are my options here are as I'm stuck with EF Core 3.1.2 that should be used in several projects targeting both .NET Core 3.0 and .NET Framework 4.7.2.
