I’m in the way of connecting my application C# (Windows Forms) with a database in .MDF, which is already inserted in the project folder.
On the computer of the course worked normally, but at home I already put the name of the instance of SQL Server but I can not connect to the database, returns the following message
I am using SQL Server Developer 2012. The name of the instance is the name that is on Wizard SQL Server Configuration System.
You have installed sql server or express on your machine?

Please edit your question and enter the section data
<connectionStrings>of yourWeb.config?– Leonel Sanches da Silva
I’m sure it’s a problem in the web.config connectionString.
