Here's a good resource for connection strings: http://www.connectionstrings.com/

There is no difference in the connection strings. The drivers are different but the connection string is the same. Make sure you installed the correct drivers.

connection strings for 64 bit os are not different at all.
I was fool to think that actually i was making mistake in server name of my connection string
if some one gets stucked then i think to help then i should tell what i did i ran below query in sql

select @@SERVERNAME AS instance_name
 

What name you get as output should be your server name
i was typing server name as xyz and actually it was xyz\SQLEXPRESS
Thanks hope it helps someone
