sdk: Warning MSB4011: "Microsoft.CSharp.targets" cannot be imported again.

Steps to reproduce

dotnet build

Expected behavior

No build warnings

Actual behavior

C:\Program Files\dotnet\sdk\2.0.3\Sdks\Microsoft.NET.Sdk\Sdk\Sdk.targets(41,3): warning MSB4011: “C:\Program Files\dotnet\sdk\2.0.3\Microsoft.CSharp.targets” cannot be imported again. It was already imported at “C:\Projects\SomeProject.csproj (106,3)”. This is most likely a build authoring error. This subsequent import will be ignored.

Environment data

This is what a regular console app csproj file looks like:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp2.0</TargetFramework>
  </PropertyGroup>

</Project>

With this, I don’t see the error you are mentioning above.
