connection string in with a local db c# windows forms

Question

I've created a database using Visual Studio 2015 by adding it locally as a mdf file

following this guide: Walkthrough creating a local database SQL Server Express

The exception that gets thrown is Format of the initialization string does not conform to specification starting at index 81.

I'm building a Windows Forms application.

My connection string looks like this string cs = @"Data Source=(LocalDB)\\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\\TestDb.mdf;Integrated";

You can user Visual Studio's server explorer to connect to your DB and then you'll get the correct connection string:
