We had only two issues to triage so this might have been a five-minute meeting but we tacked on a hootenanny of a discussion about how we're going to deal with NuGet packages in the new world of WiX v4.0's micro-repos.
Light fails with error about not finding a directory, from @kskalski, shows a particularly odd error coming from building a .cab. As that's generally working -- I'm pretty sure we would've heard about it otherwise -- we're pretty sure it's an environment-specific problem. We came up with a couple of suggestions and will wait to hear back.
WixQuietExec incorrectly assumes Unicode output encoding if first read is a single byte, from @gberesford, shows an edge case where a single character read from the output of a
WixQuietExeccustom action process tricks the code into incorrectly thinking the output is Unicode instead of ANSI. The reporter's analysis looks sound, so we took the issue into WiX v4.0.
