I am upgrading an old VS project that was built using Sitecore 7.2. I have changed the target .NET Framework to 4.7.1. Now I am trying to install Sitecore.Kernel v9.1.1 via Nuget. However when I try to do that I get the following error:

Could not install package 'Microsoft.Extensions.DependencyInjection.Abstractions 2.1.1'. You are trying to install this package into a project that targets '.NETFramework,Version=v4.7.1', but the package does not contain any assembly references or content files that are compatible with that framework.

I have also attempted to install the Microsoft.Extensions.DependencyInjection.Abstractions package separately but I get the same error. No matter what I do I can't install Microsoft.Extensions.DependencyInjection.Abstractions. What's really strange is that if I create a brand new solution that targets .NET 4.7.1 I can install if fine. So there must be something strange in my existing project/solution that is preventing me from installing Microsoft.Extensions.DependencyInjection.Abstractions 2.1.1.

Any ideas?

  • Is all projects in the Solution has the target framework set to 4.7.1? – Hishaam Namooya Apr 15 '19 at 18:00
  • Yes all projects target .NET Framework 4.7.1 – Corey Burnett Apr 15 '19 at 18:09
  • Can you remove all the references and then start by adding the different nugets – Hishaam Namooya Apr 15 '19 at 18:09
  • Assuming you're on a recent nuget, close VS and try running nuget.exe locals -clear all. Then try installing again. – Mark Cassidy♦ Apr 15 '19 at 20:03

The answer was to update Visual Studio from 15.0 to 15.9. Once I did that then the installation from Nuget worked. Who would have guessed. :)
