Type 'Object' is defined in an assembly that is not referenced (NET Standard 2.0/.NET Framework 4.6.1)

<t>I'm using the .NET Standard 2.0 preview, on which my Class Libraries are based. 
 
After having trouble with a few NuGet packages, especially regarding archive extraction, I decided to migrate my .NET Core 2.0 Console projects back to the .NET Framework 4.6.1. 
 
The .NET Framework 4.6.1 is supposed to implement the .NET Standard 2.0 specification - according to different sources. Especially the dotnet/standard GitHub Repo. 
 
Unfortunately, the migration to the .NET Framework resulted in the following errrors throughout all of .NET Framework Console projects: 
 
 
 
Error CS0012 The type 'Object' is defined in an assembly that is not referenced. You must add a reference to assembly 'netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'. 
 
Where Object can be anything: Enum, Task, ... 
 
How would I reference .NET Standard 2.0 class libraries with .NET Framework (4.6.1) without getting such errors?</t>

<t>Try to add a reference to netstandard in web.config as below:

<system.web> <br/>
   <compilation debug="true" targetFramework="4.7.1"> <br/>
      <assemblies> <br/>
         <add assembly="netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51"/> <br/>
      </assemblies> <br/>
    </compilation> <br/>
</system.web><br/>
<br/>
```</t>
