Question

Is it possible to create a profile that contains a connection string or points to a connection string in the app.config? I’d like to have a single project that can create multiple services based on which profile is passed when I execute NServicebus.Host.exe.

So something like this:

public class Warehouse1 : IProfile
{
     // Code goes here to set the connection string to the Warehouse1 DB
}

public class Warehouse2 : IProfile
{
     // Code goes here to set the connection string to the Warehouse2 DB
}

When I execute “NServicebus.Host.exe Warehouse1” I want my Publisher to use the connection string I set and use a different connection string when I execute “NServicebus.Host.exe Warehouse2”.

Answer 1

You could wrap your connection string behind a interface and do:

public class Warehouse2ProfileHandler : IHandleProfile
{

public void ProfileActivated

{
//using the nsb api

Configure.Instance.RegisterSingleton(new Warehouse2CSProvider());

//or use your container of choice
//….

}

}

More on lifecycle awareness here: (the syntax has changes since I wrote the post but you’ll get the idea)

Hope this helps!
