The type x exists in both y and z (Visual Studio 2017 and .net Core)

I have a "file->new project->new asp.net core mvc" (.net Core 1.1) and have installed two Nuget Packages:

  • System.Globalization
  • System.Text.Encoding

Both version 4.3 as seen in the solution explorer. The error relates to a lower version 4.2. The csproj also references the 4.3 version. So where is the 4.2 ref? enter image description here

If I uninstall the 4.3.0 version I get a 4.0.10 and 4.2.0 conflict...

blabla.cs(117,23): error CS0433: The type 'Encoding' exists in both 'System.Text.Encoding, Version=4.0.10.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' and 'System.Runtime, Version=4.2.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'

edit is this perhaps browserlink related and if so, how can I fix it? https://stackoverflow.com/a/43571044/169714

edit2 @Ilya Chumakov referenced this other stackoverflow topic. So I searched the solution explorer for the globalization or encoding and all I got were references to the 4.3 (which is the nuget version) enter image description here enter image description here

Fixed by removing the browserlink package in the solution explorer under dependencies -> nuget

https://github.com/NuGet/Home/issues/4484#issuecomment-277863709

and remove app.UseBrowserLink(); from public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory) in Startup.cs
