Own implementation of a vector class with a visualizer
By default visual studio does not support rendering third-party arrays (just like a vector).
For the visualizer to work for the vector class, you need to move the file 'Vector_.natvis' to
'(Drive where VS is installed):#UserName#\Documents\Visual Studio {Visual Studio version (in my case 2022)}\Visualizers'
in this folder leave this file, then run the project and in debugging it will work.
Example path: 'C:\Users\Sergey\Documents\Visual Studio 2022\Visualizers\Vector_.natvis'
