Question

I am experiencing the following NU1605 dependency errors in my netcoreapp2.0 console application:

Answer 1

Make sure that you are using same version for build and publish you can fix it adding 2.1.9 in .csproj file under PropertyGroup this should match with your current settings version. Ex:

  
      Exe
      netcoreapp2.1    
      2.1.9 
  

Error which I got was: NETSDK1061: The project was restored using Microsoft.NETCore.App version 2.1.9, but with current settings, version 2.1.0 would be used instead.
