Merge changes for 2.0.3 to release

[prafullbhosale]

Fixes issues:

• #633 PR #667
• #663 PR #658

Changes from release/2.0 are already rebased into the pb/placeholder_2.0.x branch.

These fixes have already been ported to dev.

I didn't review product changes carefully, but I didn't see infrastructure changes, so from me.

Once this is merged, can you also update the Scaffolding submodule on the release/2.0 branch in aspnet/Universe? If you're not familiar with git submodules, I've written some instructions here.

Unfortunately I don't know this codebase at all so I'm not sure I'll be any good at reviewing the functional changes. But I'm with @natemcmaster that as long as the product changes are good, this is good 😄

[prafullbhosale]

The functional changes were already reviewed as part of the PRs mentioned above.
Going to merge this now and update the submodules in universe.

[prafullbhosale]

Don't seem to have write access to Universe. @Eilon could you please provide access?

[natemcmaster]

I'll take care of updating the submodule.

[Eilon]

@prafullbhosale you should have access now too, in case you need to do it again in the future.
