Magnet 1.0.2

What is Magnet?

Magnet�ǻ��ڡ�Microsoft.CodeAnalysis.CSharp.Scripting������һ�������ܵ�c#��Ϸ�ű�����

Magnet is based on "Microsoft.CodeAnalysis.CSharp.Scripting" to develop a high performance c # game Script engine

��c#���Ժ�NET����£��ű����а�ȫ���ɿء���״̬�õ��ص�

On the basis of C# language and.NET framework, the script is safe, controllable, flexible and state
