Bounty: 50
I was able to upgrade my .NetStandard2.0 project to use EntityFrameworkCore 3.1.4 and created a nuget package.
Now I want to use that nuget package in my netcoreapp2.2 project.
However, when I try to add the package via nuget I get
Error NU1107 Version conflict detected for Microsoft.EntityFrameworkCore. Install/reference Microsoft.EntityFrameworkCore 3.1.4 directly to project MyApi to resolve this issue.
MyApi -> SBDSTD.Standard 1.0.0-CI-20200526-230146 -> Microsoft.EntityFrameworkCore (>= 3.1.4)
MyApi -> Microsoft.AspNetCore.App 2.2.0 -> Microsoft.EntityFrameworkCore (>= 2.2.0 && < 2.3.0). MyApi D:devMyApiMyApiMyApi.csproj 1
So I tried to install the Entity Framework Packages using
Install-Package Microsoft.EntityFrameworkCore -Version 3.1.4
I got
NU1608: Detected package version outside of dependency constraint: Microsoft.AspNetCore.App 2.2.0 requires Microsoft.EntityFrameworkCore (>= 2.2.0 && < 2.3.0) but version Microsoft.EntityFrameworkCore 3.1.4 was resolved.
Install-Package : NU1107: Version conflict detected for Microsoft.EntityFrameworkCore.Abstractions. Install/reference Microsoft.EntityFrameworkCore.Abstractions 3.1.4 directly to project
MyApito resolve this issue.
MyApi-> Microsoft.EntityFrameworkCore 3.1.4 -> Microsoft.EntityFrameworkCore.Abstractions (>= 3.1.4)
MyApi-> Microsoft.AspNetCore.App 2.2.0 -> Microsoft.EntityFrameworkCore.Abstractions (>= 2.2.0 && < 2.3.0).

I aren’t willing to start trying to install the suggested package because I have just lost half a day doing similar things in the Package Manager UI
