How Microsoft Uses C++ to Deliver Office - Huge Size, Small Components - Zachary Henkel - CppCon 2022
https://github.com/CppCon/CppCon2022
Office is one of the largest and longest-lived C++ codebases in the world. Over 40 years Office has evolved from a single application written in C for DOS to a product containing over 100M lines of C++ code targeting more than a dozen platforms. What are the implications of growing to this size and what sort of engineering is required? In this talk I’ll give a glimpse behind the curtain on the C++ engineering and architecture in Office. In addition to sharing some details on the scale of Office, I’ll describe the design and coding standards used to create well-factored components that we have termed liblets.
