HttpClient appears to be broken when running on Mono with the latest release.
Repro (from stefan-schweiger): https://github.com/stefan-schweiger/mono-http-core-repro
This is due to the way how we bundle Microsoft.NET.Build.Extensions. It contains .NET framework specific implementation of core libraries which when used on Mono fail.
We should not distribute their version at all as we already have correct version in mono.
One of the exhibits is the presence of full System.Net.Http.dll assembly in net461/lib but there are more in this or other folders (System.IO.Compression, System.Runtime.InteropServices.RuntimeInformation, etc)
No resolution beyond hacks for this critical issue yet?
I also would appreciate a solution for that problem.
As a workaround the following works for me:
Include this into the UITest project file:
<Delete Files="bin/$(Configuration)/System.Net.Http.dll" />
this is breaking all uitest running locally, we should fix this ASAP. as Xamarin.Forms now is netstandard 2.0 it will break all our users when they upgrade.
Ankit, could you look into this ASAP
This also affects 184.108.40.206
This should be fixed in Mono 5.12 and newer
