Hello：）
Please make sure that you've referred the EntityFramework.dll successfully，and then refer the namespace of
using System.Data.Entity;
And then directly use DataBase.SetSerializer(……); But your class should also implement the interface of IDatabaseInitializer<TContext>.

For an example of how to call SetInitializer, see this tutorial:

All you need to do is make reference to the System.Data.Entity and your App's model namesspaces. Like so:
That should do the trick.
