See http://wiki.ros.org/Installation/Windows to install ROS noetic on Windows, and then open the ROS Command Window shortcut.

Check using set command if you have special characters in some environment variables and remove them if needed since it may cause problems, e.g. I got 
OneDrive=C:\Users\Administrator\OneDrive - Ecole Nationale Supérieure de Techniques Avancées Bretagne
OneDriveCommercial=C:\Users\Administrator\OneDrive - Ecole Nationale Supérieure de Techniques Avancées Bretagne
which have special characters, so I remove those variables temporarily
set OneDrive=
set OneDriveCommercial=

To create a simple project, we can take http://www.clearpathrobotics.com/assets/guides/kinetic/ros/Creating%20publisher.html as an example
md c:\catkin_ws\src
cd c:\catkin_ws\src
catkin_init_workspace
catkin_create_pkg random_driver roscpp std_msgs
rem Create Main.cpp and edit CMakeLists.txt, see https://www.ensta-bretagne.fr/lebars/tutorials/catkin_ws_hello.zip, or https://github.com/ENSTABretagneRobotics/SATURNE_simulation (which needs https://github.com/lebarsfa/Packages/tree/main/choco/ros-noetic-hector_gazebo_plugins) for a more complicated project
cd ..
devenv (open C:\catkin_ws\, set in C:\catkin_ws\src\CMakeSettings.json everything in RelWithDebugInfo (if ROS installed in Release, see https://stackoverflow.com/questions/21975715/rosinit-throws-an-error-windows-roscpp and https://github.com/Brabalawuka/RosOnWindows) "generator": "NMake Makefiles", "buildRoot": "${workspaceRoot}\\build", "installRoot": "${workspaceRoot}\\install",  "cmakeCommandArgs": "-D CATKIN_DEVEL_PREFIX=\"${workspaceRoot}\\devel\"", then you can debug)

Otherwise, it is also possible to build and run outside Visual Studio IDE
catkin_make
devel\setup.bat
rosrun random_driver node
rem If the wrong Python version appears to be used, try to remove any other Python version from Windows PATH, or try also something like catkin_make -DPYTHON_EXECUTABLE=%ROS_ROOT%\..\..\python.exe...
rem To debug, see https://docs.microsoft.com/en-us/visualstudio/debugger/debug-multiple-processes?view=vs-2019#BKMK_Automatically_start_an_process_in_the_debugger
