<!-- When we load a project in Visual Studio, the project system first does an evaluation pass of the
project, and hands the resulting list of <Compile> items to the language service. It then does an
execution pass executing CoreCompile passing SkipCompilerExecution=true and ProvideCommandLineArgs=true,
that resulting command line string is where we get our compiler switches. The execution pass is much
slower than the evaluation pass, so there's a window of time where we have a list of files, but not
any options yet.
Because there's a gap, that means there's a time where we are parsing source files with the default
parse options. We'll then have to reparse them a second time which isn't great. It also means any
cache lookups we do won't have the right options either, so the cache lookups might miss.
To help this, we'll have properties for the evaluation pass which is an "approximation" of the
options that would come out of CoreCompile, but only the ones that are required to be specified
and we don't expect them to change after evaluation phase or those that matter for parsing.
It's acceptable for the options that affect parsing to be imperfect: once the execution pass is complete we'll use those options instead,
so any behaviors here that don't match the real command line generation will only be temporary, and
probably won't be any worse than having no options at all. -->
