I'm currently trying to do some JSON formatting using the HttpClient in .NET Core and MediaTypeFormatters. Especially the function "ReadAsAsync(..., MediaTypeFormatter, ...)" (https://msdn.microsoft.com/de-de/library/system.net.http.httpcontentextensions.readasasync(v=vs.118).aspx) which was available in .NET Framework in the HttpContent-Class would be very helpful. As far as I understood, it can be found in the NuGet package Microsoft.AspNet.WebApi.Client but I cannot download it because it is not supported in .NET Core.

Though I have read, that it should be:

I know that it is possible to do the formatting using Newtonsoft and so on.

But does someone know, if that package will be available in .NET Core some day again? I could not find any information really...

Update:

Microsoft.AspNet.WebApi.Client version 5.2.4 was released on 2018-02-12.

Thanks @whitney-kew @jaquez

The package is not fully compatible with dotnetcore now. However there's workaround for this. You have to edit project.csproj like below:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
   <TargetFramework>netstandard1.4</TargetFramework>
   <PackageTargetFallback>portable-net451+win8</PackageTargetFallback>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.AspNet.WebApi.Client" Version="5.2.3" />
    <PackageReference Include="System.Runtime.Serialization.Xml" Version="4.3.0-*" />
    <PackageReference Include="System.Xml.XmlSerializer" Version="4.3.0-*" />
  </ItemGroup> 
</Project>

Please refer to this github issue for details:

I think the new Microsoft.AspNet.WebApi.Client version (5.2.4) should fix this, but it's not released yet, maybe in late 2017.

Microsoft.AspNet.WebApi.Client 5.2.4-preview1 is available now at https://www.nuget.org/packages/Microsoft.AspNet.WebApi.Client/5.2.4-preview1, as of the first week of January 2018. I was able to add it to my .NET Core library today, and it builds successfully.

In addition to the other answers, there's also the System.Net.Http.Json package that uses the new Json serializer instead of Newtonsoft's.

The usage is slightly different than using Microsoft.AspNet.WebApi.Client.

httpClient.GetFromJsonAsync<Type>(uri);

There's a number of other overloads as well.
