I created an ASP.NET MVC 3 project using the default template, when I ran it and created an account, it automatically created an MDF file in my App_Data directory.
The problem is my development machine had a community preview of SQL Server ‘Denali’ installed, and the application needs to run on SQL Server 2008 R2 – so I can’t attach the MDF file to the production instance.
I’ve changed the MDF file to be a SQL Server 2008 R2 database, attached it to a local instance, and added this to my web.config file (no connection strings were present before this):
<add name="ApplicationServices" connectionString="Data Source=127.0.0.1;Initial Catalog=MyDB;Integrated Security=True"
providerName="System.Data.SqlClient" />
But my application still seems to look for the older instance, when I try to login now, I get this error:
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: SQL
Network Interfaces, error: 26 – Error Locating Server/Instance
Specified)
My question is – when Visual Studio 2010 automatically creates an MDF file for you, is there a connection string specified somewhere other than the web.config file?
I’ve searched through the code and can’t seem to find one. I’ve verified I can connect to the SQL Server 2008 R2 database from other applications.
Any suggestions are welcome.
This was an issue in my Web.config file. It’s fixed now.
