I am using Final Builder 8.0.0.2228 with the Visual Studio Solution action.
Until now, the Rebuild All option was working fine, but after upgrading to VS 2017 (15.3) with the new ‘Lightweight Solution Load’ option, my solutions are not getting built.
It seems that if I use the MSBuild option, they do get built correctly, but without this option they are **not** rebuilt.
Is this a known problem, or a problem at my end?
Thanks,
Martin.

It looks like we will have to do some investigation on this. The more info you can provide the better, what settings do you have on your actions. Better yet, send your finalbuilder project and the .sln file to support so we can be sure we are on the same page.

Hi Martin,
We have been able to reproduce the issue here. It seems that this is an issue relating to [devenv.com](http://devenv.com) not loading the solution when “Lightweight Solution Load” is turned on.
For example I setup a solution of console applications called ConsoleApps.sln.
The following is the output when “Lightweight Solution Load” is turned on for that solution:
\> “C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\[devenv.com](http://devenv.com)” /rebuild “Release|Any CPU” “C:\Users\jason\Documents\Visual Studio 2017\Projects\ConsoleApps\ConsoleApps.sln” /project “C:\Users\jason\Documents\Visual Studio 2017\Projects\ConsoleApps\ConsoleApp2\ConsoleApp2.csproj”
Microsoft Visual Studio 2017 Version 15.0.26730.3.

========== Rebuild All: 0 succeeded, 0 failed, 0 skipped ==========
With “Lightweight Solution Load” turned off the following is logged and the projects are rebuilt:
Microsoft Visual Studio 2017 Version 15.0.26730.3.
Copyright © Microsoft Corp. All rights reserved.
1\>------ Rebuild All started: Project: ConsoleApps1, Configuration: Release Any CPU ------
2\>------ Rebuild All started: Project: ConsoleApp2, Configuration: Release Any CPU ------
3\>------ Rebuild All started: Project: ConsoleApp3, Configuration: Release Any CPU ------
4\>------ Rebuild All started: Project: ConsoleApp4, Configuration: Release Any CPU ------
1\>Build started 17/08/2017 10:20:20 AM.
.

========== Rebuild All: 4 succeeded, 0 failed, 0 skipped ==========
For the meantime I suggest turning off lightweight solution loading, or have a separate solution for building (which I understand can be an overhead). We also suggest switching to using MSBuild as this seems where Microsoft is placing its efforts.

Jason:
Okay, understood. I’ll use the MSBuild for the moment.
This is not a big problem, as Lightweight Load is new to 15.3 and I was just trying it out.
Regards,
Martin.
