I had develop a application in asp.net with C#.
The theme of application is sending mail with Image(not an attachment).
I have a database more than 5000 emails.
When Iam running this application It's sending mails around 100 and then Iam getting Exception like this :
Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.
