After MTASC compiler, I read today of another upcoming SWF compiler.
NeoSwiff allows developers to write Flash™ applications in C#. NeoSwiff comes with a C# to SWF compiler, and also with a Visual Studio .NET support. This is very interesting 🙂
Moreover the compiler is available for Windows/Mac OSX and Linux
