Can't install 1.9.0 into VS2017 targeting .NET 4.5.1

[ansegura7]

Hi there,

NuGet R.Net 1.9.0 works great for .NET 4.6.1 and 4.7.2.

But I can't manage to install it on a project that is tied to the .NET 4.5.1 framework.

Any suggestions? I can't modify the target framework of the project, because it is already in production.

I got the following output:
