Microsoft.AspNetCore.SignalR.Common The exception thrown from a hub when an error occurs. Exceptions often contain sensitive information, such as connection information. Because of this, SignalR does not expose the details of exceptions that occur on the server to the client. However, instances of are sent to the client. Initializes a new instance of the class.

Represents the stream invocation message type. Represents the cancel invocation message type. Represents the ping message type. Represents the close message type. Represents the ack message type. Represents the sequence message type. Extension methods for . Converts the specified to its serialized representation. The hub protocol. The message to convert to bytes. The serialized representation of the specified message. A protocol abstraction for communicating with SignalR hubs. Gets the name of the protocol. The name is used by SignalR to resolve the protocol between the client and server. Gets the major version of the protocol. Gets the transfer format of the protocol. Creates a new from the specified serialized representation, and using the specified binder. The serialized representation of the message. The binder used to parse the message. When this method returns true, contains the parsed message. A value that is true if the was successfully parsed; otherwise, false. Writes the specified to a writer. The message to write.

Gets a value indicating whether the protocol supports the specified version. The version. A value indicating whether the protocol supports the specified version. Represents a failure to bind arguments for an invocation. This does not represent an actual message that is sent on the wire, it is returned by to indicate that a binding failure occurred when parsing an invocation. The invocation ID is associated so that the error can be sent back to the client, associated with the appropriate invocation ID. Gets the exception thrown during binding. Gets the target method name. Initializes a new instance of the class. The invocation ID. The target method name. The exception thrown during binding. A keep-alive message to let the other side of the connection know that the connection is still alive. A static instance of the PingMessage to remove unneeded allocations. Type returned to implementations to let them know the object being deserialized should be stored as raw serialized bytes in the format of the protocol being used. In Json that would mean storing the byte representation of ascii {"prop":10} as an example. Stores the raw serialized bytes of a for forwarding to another server. Will copy the passed in bytes to internal storage. The raw bytes from the client. The raw serialized bytes from the client. Represents the restart of the sequence of messages being sent. is the starting ID of messages being sent, which might be duplicate messages. Initializes a new instance of the class. Specifies the starting ID for messages that will be received from this point onward. The new starting ID of incoming messages. Represents a failure to bind arguments for a StreamDataMessage. This does not represent an actual message that is sent on the wire, it is returned by to indicate that a binding failure occurred when parsing a StreamDataMessage. The stream ID is associated so that the error can be sent to the relevant hub method. Gets the id of the relevant stream Gets the exception thrown during binding. Initializes a new instance of the class. The stream ID. The exception thrown during binding. Represents a single item of an active stream. The single item from a stream. Constructs a . The ID of the stream. An item from the stream. Holds the written segments from a MemoryBufferWriter and is no longer attached to a MemoryBufferWriter. You are now responsible for calling Dispose on this type to return the memory to the pool. Holds a byte[] from the pool and a size value. Basically a Memory but guaranteed to be backed by an ArrayPool byte[], so that we know we can return it. Throws an if is null or an if it is empty. The reference type argument to validate as neither null nor empty. The name of the parameter with which corresponds. Throws an if is null. The reference type argument to validate as non-null. The name of the parameter with which corresponds.
