Doesn't connect with xamarin forms

[neville-nazerane]

When I try the following

1. Create a new Xamarin Forms project
2. Update all release packages
3. Run Install-Package Microsoft.AspNetCore.SignalR.Client -Version 1.0.0-preview1-final on the portable project
4. Run the android project

I find the following error:

"Could not load assembly 'System.Threading.Tasks.Extensions' during startup registration".

I have tried installing the latest pre-release of System.Threading.Tasks.Extensions. Still no change in the error.

Update
I have found the same error on xamarin versions "2.5.0.122203", "2.5.0.280555", "2.5.1.317207-pre1"

I get the same error with web socket client nuget as well for "2.5.0.280555" and "2.5.1.317207-pre1" but NOT on "2.5.0.122203".

Are you using the latest version of Xamarin?

[neville-nazerane]

Yes, I install create a new Xamarin Forms project and update all nuget packages (without pre-releases) and then to ahead with step 3.

Wrt the AOT compilation error, I've put together a simple repro on github and explained the issue on stackoverflow.
