SignalR HandshakeProtocol.SuccessHandshakeData removed and replaced with helper method

The HandshakeProtocol.SuccessHandshakeData field was removed and replaced with a helper method that generates a successful handshake response given a specific IHubProtocol.

Version introduced

3.0

Old behavior

HandshakeProtocol.SuccessHandshakeData was a public static ReadOnlyMemory<byte> field.

New behavior

HandshakeProtocol.SuccessHandshakeData has been replaced by a static GetSuccessfulHandshake(IHubProtocol protocol) method that returns a ReadOnlyMemory<byte> based on the specified protocol.

Reason for change

This change was made because additional fields were added to the handshake response that are non-constant and change depending on the selected protocol.

Recommended action

None. This type is not designed for use from user code, it is public so it can be shared between the SignalR server and client. It may also be used by customer SignalR clients written in .NET. Users of SignalR should not be affected by this change.
