What do Yellow Warning Triangles mean on Dependencies in Visual Studio 2017?

In the build Log I happened to notice this:

C:\Program Files\dotnet\sdk\2.0.2\Sdks\Microsoft.NET.Sdk\build\Microsoft.NET.Sdk.DefaultItems.targets(199,5): warning : A PackageReference for 'NETStandard.Library' was included in your project. This package is implicitly referenced by the .NET SDK and you do not typically need to reference it from your project. For more information, see https://aka.ms/sdkimplicitrefs

I therefore went and uninstalled all packages that were listed as dependencies for the .Net Standard nuget listed here:

.NETStandard 1.1

Microsoft.NETCore.Platforms (>= 1.1.0)

System.Collections (>= 4.3.0)

System.Collections.Concurrent (>= 4.3.0)

System.Diagnostics.Debug (>=> 4.3.0)

System.Diagnostics.Tools (>= 4.3.0)

System.Diagnostics.Tracing (>= 4.3.0)

System.Globalization (>= 4.3.0)

System.IO (>= 4.3.0)

System.IO.Compression (>= 4.3.0)

System.Linq (>= 4.3.0)

System.Linq.Expressions (>= 4.3.0)

System.Net.Http (>= 4.3.2)

System.Net.Primitives (>= 4.3.0)

System.ObjectModel (>= 4.3.0)

System.Reflection (>= 4.3.0)

System.Reflection.Extensions (>= 4.3.0)

System.Reflection.Primitives (>= 4.3.0)

System.Resources.ResourceManager (>= 4.3.0)

System.Runtime (>= 4.3.0)

System.Runtime.Extensions (>= 4.3.0)

System.Runtime.InteropServices (>= 4.3.0)

System.Runtime.InteropServices.RuntimeInformation (>=> 4.3.0)

System.Runtime.Numerics (>= 4.3.0)

System.Text.Encoding (>= 4.3.0)

System.Text.Encoding.Extensions (>= 4.3.0)

System.Text.RegularExpressions (>= 4.3.0)

System.Threading (>= 4.3.0)

System.Threading.Tasks (>= 4.3.0)

System.Xml.ReaderWriter (>= 4.3.0)

System.Xml.XDocument (>= 4.3.0)

And the yellow warnings disappeared.

I have also found you can use the NoWarn property like below:

<ItemGroup>
  <PackageReference Include="Huitian.PowerCollections" Version="1.0.0" NoWarn="NU1701" />
</ItemGroup>
