Xamarin.iOS - Could not install package 'System.Net.Http 4.0.0' the package does not contain any assembly references

Question

I am trying to install the NuGet package System.Net.Http on my IOS project. But running into this error:

Error: Could not install package 'System.Net.Http 4.0.0'. You are trying to install this package into a project that targets 'Xamarin.iOS,Version=v1.0', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author

I use the HttpClient in my SharedProject to download and parse a webpage. I can add the reference to the IOS package, but when I debug the project the HttpClient is always a "Unknown identifier".

My Solution runs perfekt in Android, Universal App and Windows Phone 8.1

I am using VS2015.

通过在Xamarin Studio中安装软件包来解决此问题，然后切换回Visual Studio。
