How to generate the connection string for MS SQL Server

This short article is showing how to use the workaround to generate the connection string for MS SQL Server.

First you follow the link to create an ADO.NET Entity Model or you can call it Entity Framework model

After that you will find a long connection string for Entity Framework like the below.

<add name=NORTHWNDEntities connectionString=metadata=res://*/ModelNW.csdl|res://*/ModelNW.ssdl|res://*/ModelNW.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=;initial catalog=NORTHWND;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework&quot; providerName=System.Data.EntityClient />

If you think you cannot use this string for SqlConnection then you are actually right. Somehow you can extract the middle part of your connection string for Entity Framework like the one below.

data source=;initial catalog=NORTHWND;integrated security=True

Okay, this string you can use for your SqlConnection object.
