Stopped working for me with latest VS update (15.6.1)

[DevInstinct]

Been using it for more than a year.
After the VS update, all files are not nested anymore.
Tried manual nesting.
Enabled all options.
Uninstalled/re-installed File Nesting.
Nothing worked...

Did you get this resolved?

I noticed that with some of the latest updates VS keeps disabling the FileNesting extension and I have to enable it manually, but I haven't had any of the issues you described with files not being nested any more.

I still have the issue. We have a .NET 4.5.2 (output type Console.Application) and nothing nests anymore.

Have you tried going to Tools -> Options -> File Nesting? You need to make sure that nesting is enabled. By default all the options are disabled so auto nesting won't work at all.
