With Build before ReAttaching enabled if the build fails don't attach to process.

I'm using VS 2022 (Version 17.1.6) and have installed the ReAttach VSIX extension and have enabled the option Build before ReAttaching.

When I ReAttach using the extension my solution builds and then re-attaches to the last process which is what I expected it to do.

However if I make a change which stops the solution from successfully compiling the ReAttach extension runs the build as before but the build correctly fails but the ReAttach to the process still happens. I would have expected on a failed build that the ReAttach to process would not occur, highlighting an issue.

I totally agree. Apparently, that scenario was never tested. In fact, when looking at the code, the result of the actual build is not taken into account at all.

It seems like the automation object used to trigger build doesn't return anything. I guess one would need to implement something a bit more sophisticated in order to address this. E.g. IVsSolutionBuildManager might hold the key.
