I installed a Visual Studio 2019 and created a new Asp.Net core 2.1 console application project. I was trying to install NuGet package 'PDFsharp 1.50.5147' and it always gave me this warning. I have changed it to the previous versions but same things happened.
tried to match older versions of PdfSharp with .NET version 2.1 and also tired with .NET version 2.0
