Many new features in C # provide better "Impromptu programming" capabilities.

Let's start with "Impromptu programming" and search for it on the Internet. Someone actually used this word. I don't know if it means the same as what I want to express. Let's just say what I mean, when you want to complete a "function" or a "applet", you should first "Ray" The idea of the function to be written (local sound, which means "Combing ".), Then, start writing. The writing process is not interrupted, and the thinking is highly concentrated. You can keep writing according to the "established" idea until the function is completed, and then compile and run it.
There is also a word to describe this, that is, "closed-eye programming", which emphasizes not debugging. In fact, it is all about, with clear thinking and uninterrupted thinking.
However, in such a process, it is often "annoying" to "add classes", because you need to create a new file and define a class, the most annoying thing is that you still need to name this class, which interrupts your thinking.
New Features of C #, such as Anonymous types, Anonymous method, and Implicitly typed local variables, all play a very good role in promoting "Impromptu programming.
