Recommendation for a Strategy Game Engine for .NET?

Can anyone recommend a strategy game engine for the .net framework. I downloaded XNA, but it is way beyond my needs. I just want to create a turn based strategy game. I have searched and searched, but all I cannnot find any examples. I have asked for something similiar before, but have not gotten any good answers.

If the problem is that XNA doesn't do what yo want, TorqueX 2D looks like the closest you will come to an out-of-the-box solution for .NET.

If the problem is that XNA is overkill for your needs, feel free to ignore overly complicated features and work at a lower level of abstraction. For example, I recall that lots of the XNA API mirrors DirectX.
