From where do I reference a missing assembly (System.Net.Http.Formatting)?

Question

I had the same problem. I used Microsoft Asp Net WebApi Client 4.0.20710 and it worked for me.

Type the following command into Tools > Library Package Manager > Package Manager Console:

Install-Package Microsoft.AspNet.WebApi.Client -Version 4.0.20710

Adding to what Luiz answered above.

System.Net.Http.Formatting is a library and is used for media type formatting. For example: http://msdn.microsoft.com/en-us/library/system.net.http.formatting.jsonmediatypeformatter(v=vs.118).aspx

When referencing it, when I tried, I was looking to add a reference in my project and was looking in the Assemblies/Framework folder in Reference Manager.

It is actually in the Assemblies/Extensions folder in Reference Manager

If you got an error trying to install System.Net.Http.Formatting -Version 4.0.20710, try this one:

Install-Package WebApiDoodle.Net.Http.Formatting -Pre

I just found on NuGet: https://www.nuget.org/packages/WebApiDoodle.Net.Http.Formatting/3.0.0-pre01

Right click on project and click Add a reference option, then go to Extensions from Assemblies tab and choose System.Net.Http.Formatting. If it is no in here you have to manually add in prgramme files-> Microsoft ASP.NET
