c# - Item added to DbContext twice -

i new sp.net mvc, excuse me missing basic stuff.

i have created website working database (microsoft sql server) , i'm using entity framework package manage it.

i have databasemanager class following:

public class databasemanager : dbcontext  {     public dbset<connection> connections { get; set; } . . . } 

my application listens syslog connections , updates connections member accordingly:

db.connections.add(new connection(sourceip, destinationip)) db.savechanges(); 

anyway, weird may seem, when add connection dbcontext 2 connection added (both identical) instead of one.

what might problem?

if have registered event listener twice or included registering file (may js file) twice, issue come. can time check @ firebug list of events attached..
