设计项目结构时应该注意哪些事项？

Question

I think if I add a lot of class files to the project then the performance of the project will be slow. Am I thinking right?

Answer 1

Note that C# is a compiled language, therefore, all those class files are already compiled and optimized into a single solution at runtime. There exists the possibility of adding too much, always, but I think most web API projects will not even come close to such a limit that will cause application slowdown.

Just a typical empty project created in Visual Studio 2019 will have over 20 class files already in it and loads at runtime rather quickly.
