SQL Server connection on Framework 4.5.1


  • Hi Microsoft,

    What other privileges do we need to use our computers?!

    We have a problem here with all .Net applications that use SQL connection  since  the new 4.5.1 Framework is installed. Even when I create a new application in VS 2012 I cannot see any of databases on our server. The VS creates an error when try to, regardless the chosen framework number.

    There are about 100 computers in my department and we have to uninstall the new Framework on each of them as we want our apps to work.

    After uninstalling 4.5.1 and reinstalling 4.5 everything works fine.

    We did try the  “Netsh winsock reset” and reset computers many times. It helped once but with reinstalling the application and it worked only till next launch.

    We have SQL Server 2008 R2 SP2 (no antivirus on the server).

    We have also found that some of our ClickOnce applications (not only SQL connecting) need to be reinstalled to work on many computers (randomly) after FW 4.5.1 installation.

  • Hello,

    Finally I have found a solution by myself. It was very, very easy.

    But the link you sent... Well, I've lost a lot of time trying to understand it. And I’m afraid it has nothing in common with my question.

    Thanks anyway.

  • Creating a new database connection to MS SQL Server on (and for) computers with FW 4.5.1 I had to change Data provider from default  SQL Server to OLE DB. Other way the VS crushes with No Response error. It worked fine before updating to 4.5.1. The strange thing is that there is no need to change this setting on our Swedish computers. This problem only appears on Polish ones regardless the server location.
