Question

What is the simplest way to programmatically toggle back and forth between test and dev databases using the LINQ to SQL ORM?

Answer 1

When newing up a DataContext, one of the overloads takes a connection string. I would therefore have a compiler switch something like:

 #if Debug
 string connectionString = ....
 #else
 string connectionString = ...
 #endif

 DbDataContext db = new DbDataContext(connectionString);
