I have a problem establishing connection with Server Explorer in Visual Studio 2012 Ultimate with MS SQL server 2012 Express. Everything is on local machine.

You can see screen shot here - http://s16.postimage.org/4gvo7r5id/se_prob_ss1.png

With System.Data.SqlClient and SqlConnection.Open() everything work fine I'm able to connect and execute SQL scripts (with and without Windows Authentication).

What I tried so far:

  • I checked in MS SQL Management Studio in Conncetions "Allow remote connections to this server" (Checked)
  • In SQL Server Configuration Manager on my SQL server TCP/IP protocol is enabled
  • I tried to connect with turned off firewall and antivirus protection
  • I tried with new Logins (with System.Data.SqlClient.SqlConnection it work)

In the picture, the server name you are connecting to appears wrong. You indicated you installed SQL Express; it has a default instance name of SQLEXPRESS. So the server you are connecting to should be:

MILLENIUM\SQLEXPRESS

instead of just MILLENIUM.
