Microsoft.AspNet.WebApi.Client supported in .NET C

问题:

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:

• Where is HttpContent.ReadAsAsync?
• https://www.techrepository.in/consuming-rest-api-methods-in-net-core-mvc-application

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...

Thanks

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.
