.net connection pooling

Question

I don\'t get what is the syntax difference between regular connection and connection pool.

When I\'m using the using key such as:

using          


        

Answer 1

as far as i know,

connection pooling is managed by ado.net client, since making connections to db is costly operation. ado.net makes pool of connections and whenever you need a connection it tries to give it from pool. even if you say to client code to close connection, ado.net hold that connection for later use. you dont manage the pooling

connection pool is told in web.config file of application. when you use using statements , you tell that object should be disposed end of using.
