Please consider adding support for the new improved Signalr core to be used as an async data source and or server side rpc which would allow for greater mvvm spa applications
Yep, we need support for the new SignalR too. The old one doesn't work.
With the R2 2018 release we included support for SignalR 1.0.0-rc1-final. As this isn't officially rolled in to .NET Core quite yet there may be changes, but we'll continue to update the library once it officially gets release. I'll mark this as completed and you can check out how to start using SignalR with our ASP.NET Core components right here: https://docs.telerik.com/aspnet-core/helpers/html-helpers/grid/binding/signalr-binding
