Allow dotnet build while previewer is running

[ThadHouse]

Is your feature request related to a problem? Please describe.

I'm guessing this is likely going to be not solvable, but I use dotnet build from my VS terminal to build my project, instead of embedded tasks. I'm noticing that fails if I have any xaml preview opened, since the output dlls are locked for the xaml previewer.

Describe the solution you'd like

It'd be really great if either somehow dotnet build could be hooked into, or maybe the previewer process needs to shut down every time after opening. I'm not really sure what the best solution is. Just something I noticed when the updated extension popped up this morning.

Describe alternatives you've considered

Essentially just not using the previewer is the option. I've went and disabled the previewer automatically showing up because of this, it was blocking my builds.

I've a few ideas, but want to get input from the folks working on the new previewer. Will report back when I've something concrete to share.

I'm running into this as well, using a custom build task running dotnet build. It would be great to have this fixed, as hitting Ctrl+Shift+B is kind of muscle memory at this point.

Maybe a "simple"™️solution could be to copy all the .dlls to some temp directory whenever the original ones change, and run the previewer from there? Anyway, it's good to see work happening on the VS Code extension, thanks to everyone involved!

@seleborg, we're mid-sprint on a new version of the Previewer, so I can dig into this once that work is complete.
