Access to entities at the first time fails

[sajjadlove]

Hi
we are using Entity Framework 4, Silverlight, dotConnect and oracle 11g.
Our login process is stored procedure but after the login we use EF to fetch data. But for the first time when we want to fetch, it causes time out and after refreshing explorer everything is good...

what's the reason of this problem?
