As event store / snapshoting => NEventStore (in my case I'm using SQL Server as the DB)
As state store => SQL Server
How to use it?
Just change the connection strings in the BankAccount.Client project (web.config).
Build the solution (enable restoring of the nuget packages in visual studio).
That's it!
It is the "same" project as the one under "cqrs-event-sourcing" repository except that I used an in-memory-process-manager (aka Saga), instead of CommandHandler and EventHandler, as workflow manager.
