+.natstepfilter file for Visual Studio debugger.
+Purpose: instruct debugger to skip some functions when using StepInto (F11)
+
+To enable:
+* 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.
+
+Unfortunately, unlike .natvis files, it isn't yet possible to include this file in your project :(
+You may upvote this: https://developercommunity.visualstudio.com/t/allow-natstepfilter-and-natjmc-to-be-included-as-p/561718
