Change Entity framework database schema at runtime

Question

In most asp.net applications you can change the database store by modifing the connectionstring at runtime. i.e I can change from using a test database to a production database

Answer 1

When I create a new "ADO.NET Entity Data Model", there are two properties "Entity Container Name" and "Namespace" available for editing in design view.. Using the namespace.EntityContainerName, you can create a new instance specifying a connection string.

MyEntities e = new MyEntities("connstr");
e.MyTable.Count();

I'm not sure if this helps you or not, good luck!

Also, this is a good case for multiple layers (doesn't have to be projects, but could be).

Solution
* DataAccess - Entities here
* Service - Wraps access to DataAccess
* Consumer - Calls Service

In this scenario, the consumer calls service, passing in whatever factor determines which connection string is used. The service then instantiates an instance of data access passing in the appropriate connection string and executes the consumer's query.

Answer 2

The easiest way to solve the problem is to manualy remove all entries like 'Schema="SchemaName"' from the SSDL part of the model.
Everything works propely in this case.
