title: Connection string not valid
body: <p>I'm trying to connect to a SQL Server 2012 database using C#, both the server and program are on the same computer. When I try to connect I get an exception:</p>
  
  <pre><code>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: 25 - Connection string is not valid)
  </code></pre>
  
  <p>There is an inner exception simply saying <code>{"The parameter is incorrect"}</code>.</p>
  
  <p>I'm trying to connect using this</p>
  
  <pre><code>&lt;add name="KBLEntities" connectionString="metadata=res://*/Models.KBL.csdl|res://*/Models.KBL.ssdl|res://*/Models.KBL.msl;provider=System.Data.SqlClient;provider connection string='data source=\sql8dvlp1\v01;initial catalog=KBL;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework'" providerName="System.Data.EntityClient" /&gt;
  </code></pre>
  
  <p>any idea what parameter is incorrect?</p>
