无法连接到Windows 10上的SQL Server和使用Visual Studio 2017

Question

I am using Windows 10 and Visual Studio 2017. I am trying to connect to a database in SQL Server 2014.

Visual Studio does pick up the database as shown in the screenshot here:

The connection string is as follows:

The code is:

const string connString = "Data Source=CLEAVEN\\SQLEXPRESS;Initial Catalog=EduAssistR;Integrated Security=True";

But I still get error 26 in the browser:

I've restarted the SQL Server Browser and enable TCP and Remote connections but I still get the error.

If I use CLEAVEN\\SQLEXPRESS instead of CLEAVEN\\\\SQLEXPRESS , I get this error:

What could be wrong?

Thank you in advance.

Answer 1

I found what was wrong.

Silly silly mistake.

In the Web.config

I did not change my connection string. Once I changed it there, all was solved.

Thank you to everyone
