Is there any good implementation of actors concurrency model for .net/c#?
I have to optimize a c# routine and i think that actors model fits perfectly as a solution for my problem. Unfortunately i have experience only with scala implementation.
These frameworks would allow you develop loosely coupled services that fulfill most of the actor-approach requirements.
Axum would be the best fit, unfortunately it's still in some sort of alpha/beta phase (UPDATE it has been killed in Feb. 2011). I use it for my research and must say that the general direction is great and it has enormous potential.
Not C# but C++ is Microsoft's Asynchronous Agents Library which gives you all the features that you need.
Have a good look at Parallel related features of .NET 4.
Hope it helps!
