I have installed VS2017 15.3.0 and .NET Core 2.0 and have created a default Web MVC application on VS 2017 and I got the following errors:
Error NU1202
Package System.Threading.Overlapped 4.0.1 is not compatible with netcoreapp2.0 (.NETCoreApp,Version=v2.0). Package System.Threading.Overlapped 4.0.1 supports: netstandard1.3 (.NETStandard,Version=v1.3)

xamarintvos10 (Xamarin.TVOS,Version=v1.0)
xamarinwatchos10 (Xamarin.WatchOS,Version=v1.0)
The same errors occours using NET CLI with the command: dotnet new mvc
I've tried update nuget: Install-Package NuGet.CommandLine -Version 4.3.0
But it doesn´t works.
So I have dotnet core2 installed, with Visual Studio 2017 with update 15.3.0 and NuGet 4.3.0
What am I missing here?

I had a similar issue, albeit with different assemblies, and the suggestion from MS was to run the following command in the Package Manager Console:
PM> dotnet nuget locals all --clear
