entity framework 4 - Dbcontext creation for multiple server Connections -

how create dbcontext manually in entity framework different database connections?

first can have multiple named connection strings in app.config file below:

<connectionstrings>     <add name="todoconnectionstring" connectionstring="data source=mylocalbox;initial catalog=tododbcodefirst2;integrated security=true;multipleactiveresultsets=true;" providername="system.data.sqlclient" />     <add name="stackoverflowentities" connectionstring="metadata=res://*/model1.csdl|res://*/model1.ssdl|res://*/model1.msl;provider=system.data.sqlclient;provider connection string=&quot;data source=.;initial catalog=stackoverflow;integrated security=true;multipleactiveresultsets=true;app=entityframework&quot;" providername="system.data.entityclient" />   </connectionstrings> 

now can define 2 different custom classes inherited dbcontext class shown below:

using system.data.entity;  namespace efdevelopment {     public class todocodefirstdbcontext : dbcontext     {         public todocodefirstdbcontext()            : base("name=todoconnectionstring")//connection string 1st db         {         }          public dbset<todo> todos { get; set; }     }      public class todocodeseconddbcontext : dbcontext     {         public todocodeseconddbcontext()           : base("name=stackoverflowentities")//connection string 2nd db         {          }          public dbset<todo> todos { get; set; }     } } 

now inside main program (i've used console application) instantiate respective entity framework (ef) context classes per need of connecting them appropriate database shown below:

class program {         static void main(string[] args)         {               using (var db = new todocodefirstdbcontext())               {                   //write code here first db connection               }                using (var db = new todocodeseconddbcontext())              {                   //write code here second db connection              }         }   }
