xtd is composed of several libraries
These libreries are grouped by theme :
system : The xtd.core library is modern c++17/20 library of classes, interfaces, and value types that provide access to system functionality. It is the foundation on which c++ applications, components, and controls are built.
drawing : The xtd.drawing library contains types that support basic GDI+ graphics functionality. Child namespaces support advanced two-dimensional and vector graphics functionality, advanced imaging functionality, and print-related and typographical services. A child namespace also contains types that extend design-time user-interface logic and drawing.
forms : The xtd.forms library contains classes for creating Windows-based applications that take full advantage of the rich user interface features available in the Microsoft Windows, Apple macOS and linux operating system.
tunit : The xtd.tunit library is a unit-testing framework for modern C++17/20. Initially ported from Microsoft.VisualStudio.TestTools.Cpp.
