Can't use Newtonsoft.Json

[Bizarrus]

How i can use Newtonsoft.Json in SharpDevelop on my WPF-Application?

Informations

SharpDevelop Version : 5.1.0.5216-0e58df71
.NET Version         : 4.7.03056
OS Version           : Microsoft Windows NT 6.3.9600.0
Current culture      : German (Germany) (de-DE)
Running under WOW6432, processor architecture: x86-64
Working Set Memory   : 329788kb
GC Heap Memory       : 97095kb

When i try to add the package over Project > Manage Packages... following error appears:

'Newtonsoft.Json' already has a dependency defined for 'Microsoft.CSharp`.

By using using Newtonsoft.Json;, SharpDevelop says:

Using directive is unnecessary. The type or namespace name 'Newtonsoft' could not be found (are you missing a using directive or an assembly reference?)

Update

When i try to install the "depencie"/"higher package", it will shown following errors:

Json.NET
    > Microsoft.CSharp
        > NETStandard.Library
            > Microsoft.NETCore.Platforms
                > The 'Microsoft.NETCore.Platforms 2.1.0' package requires NuGet client version '2.12' or above, but the current NuGet Version is '2.8.60723.765'.

Your dll is for .net core, not .net framework. why did you use SharpDevelop for .net core?
