@ericstj any advice here? Or should we direct the question to EPPlus / EPPlus.Core owners?

[ericstj]

The EPPlus.Core package supports netstandard1.3. NETStandard1.3 is supported by .NET 4.6, not .NET 4.5.2. See https://github.com/dotnet/standard/blob/master/docs/versions/netstandard1.3.md. You can retarget your application to net46 or ask the EPPlus.Core owners to make a version that supports netstandard1.2 or cross-compiles for net452.

thank you I retarget my app to net46 and its work

[robeverett]

Are there any other packages or dependencies needed to get to work with .net core 2.1 ?

[ericstj]

Not that I'm aware of, .NETStandard1.3 libraries work with .NETCore 2.1. You should probably take these questions to teh EPPlus or EPPlus.Core repositories though.
