Package .NET Standard library as Nuget package and include all project dependencies / references

When I try to use the built-in feature of creating Nuget packages in VS 2017 (for a .NET Standard class library), it doesn't include any dependencies (project references), it includes only the DLL of the current project...

Here is my project file:

<Project Sdk="Microsoft.NET.Sdk">
.
.
  <PropertyGroup>
    <TargetFrameworks>netstandard1.6;net47</TargetFrameworks>
    <PreserveCompilationContext>true</PreserveCompilationContext>
    <PackageRequireLicenseAcceptance>False</PackageRequireLicenseAcceptance>
    <GeneratePackageOnBuild>True</GeneratePackageOnBuild>
    <IncludeBuildOutput>True</IncludeBuildOutput>
    <IncludeContentInPack>True</IncludeContentInPack>
    <DevelopmentDependency>False</DevelopmentDependency>
  </PropertyGroup>
 .
 .
 </Project>

I tried different values for: DevelopmentDependency, IncludeContentInPack, IncludeBuildOutput, and it is the same.

I tried also on VS 2017 preview release as well.
