@Ahmed-Elbossily , problem in your sending data or on backend(when it parse your data). Problem not in this package.

You need to contact a backend representative and discuss this problem with him.

[Ahmed-Elbossily]

I make desctop client work well not closed
And also i make web client work well not close signalr

[Dimolll]

@Ahmed-Elbossily problem may be in your sending data.
I see your issue in other signalR client jamiewest/signalr_core#69

You must check your sending data.
