Access Instance of a Class from a differente Process in C#
I have a project called "Core" that declares an Interface. And i have a project called "Service" that instantiates a class that implements that interface (it references the "Core" project on it's dependencies).
Both projects run independently, as i can run "Core" (it's an EXE). If i do, i'd like to verify if "Service" is running, and if so, get the instance of a class that is created on the "Service" process and call it's method.
It looks like this (almost).
On "Core" project:
namespace Core
{
public interface IController { void Update(long ID, string Value, string Components); }
public static class Utils
{
public static IController Controller;
internal void Main(string args)
{
//Here, if "Service" is running, then get "Controller" from it
}
}
}
On the "Service" project:
namespace Service
{
internal class ControlMe : Core.IController
{
public void Update(long ID, string Value, string Components)
{
//Do other things
}
internal void Main(string args)
{
Core.Utils.Controller = new ControlMe();
}
}
}
It should marshal somehow from one process to another, but i'm unfamiliar with Interop methods that would call that.

Be sure to changeinternal class ControlMetopublic class ControlMe. I think you'll have issues with it beinginternalgiven your use case.

Process interop is quite limited, intentionally. You'll have to use the interop mechanisms provided by .NET. Named pipes, sockets, WCF and a few not worth mentioning because they are way too hard to get right. Don't do it is the only good advice.

the internal/public should no be an issue since the class would be captured by an interface reference; the idea is not to instantiate a new one, but capture one that's already running through differente appdomains; maybe the MarshalByRef is the way to do it - did not get yet hou to prevent multiple instances, but i'm reading about it
