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 suitable global properties in advance. It can be done by invoking the global "AppDomain.CurrentDomain.SetData" with parameter name, respectively, "lightstreamer.client.defaultConnectTimeout" and "lightstreamer.client.defaultReadTimeout" and an int value expressed in milliseconds. Note that the read timeout set will apply to the whole life of the socket and it should be far greater than the timeouts specified in the ConnectionInfo parameter. By the way, these settings will also apply to connections used for subscriptions and other control requests.  

Edition Note: Connections from the .NET Client Library are not supported by the Server, if it runs in Allegro edition.
