After consuming .net standard projects in a .net framework(4.6) console application, the dependencies of the .net standard projects are not copied into the output directory.
After going through an article by Scott Hanselman, below solution worked like a charm.
Add below line in the first "PropertyGroup" tag of the .net framework console application's ".csproj" file
<RestoreProjectStyle>PackageReference</RestoreProjectStyle>
There will not be any need to add again the .net standard projects' nuget dependencies in the console application.
Another answer is to publish the project:
dotnet publish -o path/to/output/folder
