+.natstepfilter file for Visual Studio debugger.
+Purpose: instruct debugger to skip some functions when using StepInto (F11)
+
+Since Visual Studio 2022 version 17.6 Preview 2 (currently available as a "Preview" build on March 14, 2023)
+It is possible to add the .natstepfilter file to your project file and it will automatically be used.
+(https://developercommunity.visualstudio.com/t/allow-natstepfilter-and-natjmc-to-be-included-as-p/561718)
+
+For older Visual Studio version prior to 2022 17.6 Preview 2:
+* copy in %USERPROFILE%\Documents\Visual Studio XXXX\Visualizers (current user)
+* or copy in %VsInstallDirectory%\Common7\Packages\Debugger\Visualizers (all users)
+If you have multiple VS version installed, the version that matters is the one you are using the IDE/debugger
+of (not the compiling toolset). This is supported since Visual Studio 2012.
