How To: Manage singletons of similar type in Prism with DI/IoC
Apologies in advance… I’m new to DI/IoC, Prism and it’s been a long 12 hour day!
The project I’m working on must support communications for TcpIp, Bluetooth LE, and (Serial if available). Each connection type will implement IConnection (see below), and a type specific interface (i.e. IBluetoothConnection, ITcpIpConnection, and ISerialConnection) to encapsulate the respective connection parameters. (Baud Rate, Parity, Flow Control, IP Address, Port #, etc…)
public interface IConnection
{
bool Connected { get; }
bool Connect();
bool Disconnect();
bool Tx(string message);
string Rx();
}
public interface IBluetoothLeConnection : IConnection
{
int BaudRate { get; set; }
int Parity { get; set; }
int FlowControl { get; set; }
}
public interface ITcpIpConnection : IConnection
{
string IP { get; set; }
int Port { get; set; }
}
public interface ISerialConnection : IConnection
{
string CommPort { get; set; }
int BaudRate { get; set; }
int Parity { get; set; }
int FlowControl { get; set; }
}
I plan to register all three as singletons.
containerRegistry.RegisterSingleton<IBluetoothConnection, BluetoothLeConnection>();
containerRegistry.RegisterSingleton<ITcpIpConnection, TcpIpConnection>();
containerRegistry.RegisterSingleton<ISeialConnection, SerialConnection>();
Define IConnection Connection in ViewMainBase, and then point it to the chosen concrete connection at runtime.
Questions
Will this work?
Is there a better way (best practice) or (DI/IoC magic) to accomplishing this?
Should I create a ConnectionManager class, and inject all three IConnection types into the constructor and let it manage the active connection?

Why areIBluetoothLeConnection,ITcpIpConnection, andISeialConnectioninterfaces? How are they polymorphic? Will there be more than one implementation of each of them?

Hey @MarkSeemann they are polymorphic as each interface implements IConnection I'll probably implement an abstract base class for IConnetion and subclass the other three from it.

IConnectionis already polymorphic. Why do you need further polymorphism?

Yes.

I'd refactor the ref parameter from Rx into something else because it's not easily mockable when you're writing your tests using a framework like Moq.

Yes.
