Illustrates solution-wide PRE/POST 'events' for build-operations from Visual Studio IDE (i.e. primary from VS IDE and msbuild.exe as optional)
Alternative for IVsUpdateSolutionEvents2/IVsUpdateSolutionEvents etc.
-
Variant 3: based on idea 'Map of projects'.
Problems for this variant:
* Unavailable projects - for example, if user clicked on 'Unload Project' in Solution Explorer.
However, it's trivial and not related as main bug.. This should be resolved with 'Reload Project'.

use env var for caching results from ProjectsMap and similar... for a quick optimization

Your solution is genious but it does not take into consideration projects' dependencies estableshed in project file. It could be easily corrected. Do you want me to send this fix?

Why not :)

btw, this is old draft that was finally implemented in https://github.com/3F/vsSolutionBuildEvent for that period.

However, part of this solution now is core of LProjectDependencies's logic in the new MvsSln: https://github.com/3F/MvsSln
Here's map example:
MvsSln_v2.0_Map.png

I mean, I remember some fixes for this, but anyway, your PR is welcomed for mentioned project too.

Thanks!

hmm, I don't use Gist so often (my today's sandbox repo on github is better way for this). More probably your changes will be just avaialble from /forks page o_O ie. to integrate this manually. Still lot of inconceivable behaviors from this service by my view (at least they finally added notifications for the past ~5 years <_<).

But if you want to contribute for related MvsSln, you need of course to push your committed changes as PR into: https://github.com/3F/MvsSln

Thank you for your excellent work.

You're welcome. Glad that was really helpful :)
I recommend you also consider to use an independent toolset like vssbe & mvssln
