DropCreateDatabaseIfModelChanges EF6 results in System.InvalidOperationException: The model backing the context has changed

Question

After migrating to Entity Framework 6 I get an error when executing unit tests on the build server.

I\'m using the DropCreateDatabaseIfModelChanges initiali

Answer 1

What works fine for me is excluding the migrations using define. Here is how:

• Create a new configuration called Test that defines TEST
• In your tests, throw an error when TEST is not defined.
• Exclude your migrations when TEST is defined:

#if !TEST
internal sealed class Configuration : DbMigrationsConfiguration
{
    //...
}
#endif

You might need to exclude all of your migrations, which isn't totally satisfying either (but I haven't tried it because I don't have any migrations yet).
