Opens a connection to the Server with the supplied parameters. More precisely, the Server will initiate a push session for this client, which will be accessed through a streaming connection or through a train of polling connections, depending on the configuration parameters. If a connection is already open, it is closed first. 

If streaming (as opposed to polling) is specified in the connection parameters and the environment does not allow HTTP streaming, then the "Stream-sense" feature, if enabled, is activated; hence, if the streaming connection has not yielded any data after a few seconds, a polling connection is tried instead. 

The method is blocking; it returns only after a connection to the Server has been established or the attempt has failed. It is possible to enforce timeouts for the socket connection task and for any further read task by setting the ConnectTimeoutMillis and ReadTimeoutMillis properties of ConnectionInfo. 

Edition Note: Connections from the .NET Client Library is an optional feature, available depending on Edition and License Type. To know what features are enabled by your license, please see the License tab of the Monitoring Dashboard (by default, available at /dashboard).
