My Windows 10 pc installed an update overnight. Today I have this message (below) when I launch SQL Server 2014 and try to 'Connect to Server'. Any ideas as to what Microsoft may have done to me please? Thanks in advance!
**A network-related or instance-specific error occurred while establishing a connection to SQL Server.

I've got problem with connecting SQL Server by SQL Server Management Studio. I installed the latest version. I want to connect by windows authentication. I tried server name like:
computer_name\SQLEXPRESS
localhost\SQLEXPRESS
127.0.0.1\SQLEXPRESS
But it still doesn't work. I'll be glad for any help with this.

I am having issues connected with SQL 2016 MSSQLLocalDb from my application. The system is a Server 2012 and I have just deployed my web application to it. I have installed SQLLocaldb 2016.
Running
sqllocaldb info
gave this response: The automatic instance MSSQLLocalDB was not created.
So I created the instance with the name MSSQLLocalDB.
But when I run the application I get this error:
