For Entity Framework (database-first or model-first; when you have a physical EDMX model file) you need to use a special type of connection string which is quite different from the straight ADO.NET connection strings everyone else has mentioned so far…

The connection string must look something like:

<add name="testEntities" 
     connectionString="metadata=res://*/Model1.csdl|res://*/Model1.ssdl|res://*/Model1.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=(local);initial catalog=test;integrated security=True;multipleactiveresultsets=True;App=EntityFramework&quot;" 
     providerName="System.Data.EntityClient" />

Inside this connection string, you’ll find the provider connection string= attribute which is basically your ADO.NET connection string:

provider connection string="data source=(local);initial catalog=test;integrated security=True;multipleactiveresultsets=True;App=EntityFramework"" 

So here, you need to change your server name and possibly other settings.

• data source=.... stands for your server (you can also use server=.....)
• initial catalog=..... stands for your database (you can also use database=....)
