The user instance login flag is not supported on this version of SQL Server. The connection will be closed, in asp.net mvc5

Question

I have upgraded my OS to Windows 10 and SQL Server 2008 R2 Express to SQL Server 2012 Enterprise Edition.

Now I am getting error "The user instance login flag is not supported on this version of SQL Server. The connection will be closed." as I have search all the link and followed all the step but not getting rid of this error.

As I don't have any user instance =.... in my connection string.

I have gone through the following links as well

Have you checked how your connection string looks like, exactly? — Roger Wolf, Aug 07 '16 at 14:28
Thanks Roger Wolf for your suggestion but my connection string doesn't contain any user instance word in it. '' — Akashkumar Bammrotwar, Aug 08 '16 at 06:15

Check your web.config file. I had faced similar issue but got it sorted after making changes in Connection String in web.config file
