The previous phase has been doing a plugin based on VS.NET2K3, which is approximately automatic generation of business code. I started from more than two months, but I have not idle time, and then add some questions about the VS plugin during the actual development process. All always dragged. The procedure finally breakthrough in the past few days, all functions can be achieved. Includes automatic addition of engineering, reference, compilation, etc. Waiting for some days, optimize the code (while removing some bugs, I have never understood that when I generate a tens of thousands of lines of code, my development environment will be fully collapsed) and release it. Yesterday, I suddenly thought that the code now produced is too life, and cannot generate the corresponding language code according to the user's choice. If you die, it is too boring. I thought that I have seen the code that CodeDom, which I have introduced before I have seen it, can dynamically call compilation, so I quickly read the CodeDom again, and I can generate C #, VB, JScript code. But just started research, I only wrote a small program. But I feel very interesting. In this case, I can let my Toolkit rewrite my Toolkit can make different programmers to generate the corresponding code according to their own preferences (the function is the same.)
