title: How to use a SQL connection string with ADO.NET Entity Data Model
body: <p>I am trying to use the ADO.NET Entity Data Model in a way that I can on the fly change which database I point too.  Changing databases may require an entirely new connection string.  Some databases are on different servers.  So I need the ability to pass my ADO.NET Entity Data Model a custom connection string formated like so 'server=severaddress;database=database1;User ID=test;Password=test1234;'</p>
  
  <p>Edited: My Entity Class implements ObjectContext.  The three constructers I can use is the default, pass in connectionString, pass in an EntityConnection.  When ever I use the overload constructers I get errors saying it doesn't recognize "server" in the connectionstring.</p>
  
  <p>I need to either instantiate my repository with a custom connection string, or be able to set it before use.</p>
