With feedbacks from several enthusiastic users, I have fixed many little bugs. Give the latest version a try. Post bugs on the forum as usual. Happy computing!
I am running into a little bit of difficulty with CLR debugger integration. In order to generate the debug symbol, I need to use LambdaExpression.CompileToMethod(). However, this method does not support DynamicExpression that I heavily rely on. So I am back to research and trying to figure out how to use Microsoft.Scripting.Debugging.dll. In the mean time, I am going to enable tracing in near future so that at least we can figure out problems through tracing.
