It is not currently possible when there is a -f|--framework argument because
we cannot force a TargetFramework global property on to the restore evaluation.
Doing so completely breaks restore by applying the TargetFramework to all
projects transitively. The correct behavior is to restore for all frameworks,
then build/publish/etc for the given target framework. Achieving that still
requires two distinct msbuild invocations.
This also changes the verbosity of implicit restore from quiet to that
of the subsequent command (default=minimal). Similar to global properties,
we cannot specify a distinct console verbosity for the /restore portion of
the overall execution. For consistency, we apply the same verbosity change
to the case where we still use two separate msbuild invocations.
This also fixes an issue where the separate restore invocation's msbuild log
would be overwritten by the subsequent command execution. However, this remains
unfixed in the case where we still use two separate msbuild invocations.
