Using Messagepack in ASP. NET Core SignalR

It ' s like JSON.
But fast and small.

Messagepack is an efficient binary serialization format. It lets your Exchange data among multiple languages like JSON. But it ' s faster and smaller. Small integers is encoded into a single byte, and typical short strings require only one extra byte in addition to the St Rings themselves.

Messagepack is an efficient binary serialization format. It allows you to exchange data between languages like JSON. But it's faster and smaller than JSON. A small integer is encoded into a byte, and the short string is just a byte larger than its length.

The use of Messagepack in SignalR is also simple:
