Change to .net standard 2.0

KuraiAndras commented 4 years ago

Since this library is not really dependent on .net standard 2.1 it should target 2.0. Ef Core, and every other dependency is 2.0 compatible and so should be this library. This pr also enables using the newest version of this library on .NetFramework

Update EF Core to 3.1.0 and other dependencies
Add langversion 8.0 since this is .net standard 2.0 some c# 8 features won't work
Fix csvhelper usage (currently it's using CurrentCulture should it use Invariant?)
Remove only non useable attribute after downgrade to netstandard 2.0
Bump package version 3.4.0

What is missing for this to be merged?
