I have SQL Server 2005, 2008 and 2012 installed on my Windows 7 64bit PC.
Here is my Configuration Manager, and I do see that the Agent is Stopped... not sure if this is required. I've split it out into two images so the size shows up larger
Here is what is shown in the VS2012 Database Explorer window. This is a SQL Server 2012 database
Here is my code
string selectSql = "select * from Tasks";
string connectionString = "Data Source=adamssqlserver;Database=master;Integrated Security=True;";
using (var cn = new SqlConnection(connectionString))
using (var cmd = new SqlCommand(selectSql, cn))
{
cn.Open(); // this is the line that throws the error message.
using (var reader = cmd.ExecuteReader())
{
//do something
}
}
As noted, the cn.Open(); line is what throws the error message shown below
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
