The nuget operation failed due to one or more packages being incompatible with your project

I was trying to install the MathNet.Numerics package to my project (a class library), when I got this error:

The NuGet operation failed due to one or more packages being incompatible with your project. The '.NETPlatform,Version=v5.0' ('dotnet') project framework is deprecated. For more information about how to migrate your projects to a supported framework, please refer to themigration document (https://aka.ms/rugr4c). Would you like to continue with the project action(s) anyways?

This error also occured when I tried to update the Microsoft.NETCore.Portable.Compatibility package. Does anybody know what is causing this issue? I don't quite get what the error is saying even after some research, and I couldn't find anyone else with this issue. Thanks.

That because in the Visual Studio 2017 15.3:

You had two ways to target .NET Standard: one was via letting a PCL target .NET Standard. The other was via the new .NET Standard project type. NuGet team disabled the UI for letting a PCL target .NET Standard because it never worked well. It sounds like we’ve accidentally broken something else that affects existing projects.

However, you can use the .NET Standard project type, i.e. File | New Project | .NET Standard | Class Library (.NET Standard) to target .NET Standard 1.x/2.x, which can still be consumed from .NET Core 1.x/2.x.

Check the blog Announcing .NET Standard 2.0 for some details

Hope this helps.
