scenario**\r\n\r\nCode lens, LUT, FSA will run more efficient in OOP. also FAR or GOTO now can run as fast as they used to be in OOP.\r\n\r\n**Bugs this fixes:** \r\n\r\nNo bug tracking this issue.\r\n\r\n**Workarounds, if any**\r\n\r\nScenario already works just not as efficient as with this change.\r\n\r\n**Risk**\r\n\r\nquite a bit of changes on how solution is created and maintained in OOP. so there is a bit of risk. it would be better for us to start dogfood sooner.\r\n\r\n**Performance impact**\r\n\r\nthis should improve perf (elapsed time) on all features that run on OOP. since having primary workspace means we now have correct versions, declaration only compilations are cached and etc. especially on features that require versions to work correctly such as FAR, GOTO, Code lens.\r\n\r\nthis should also improve overall memory usage of OOP since we no longer need to cache all data in memory as we used to. we just need them for initial solution and can get rid of them.\r\n\r\n**Is this a regression from a previous update?**\r\n\r\nno\r\n\r\n**Root cause analysis:**\r\n\r\nthis is not a regression. this is a work to improve existing code's performance.\r\n\r\n**How was the bug found?**\r\n\r\nmain issue with previous implementation was that, it always re-created solution from scratch. so FAR, GOTO, CodeLens couldn't use cache incrementally. now, those features should be able to. versions in OOP is not same as ones in InProc but, versions should be consistent within OOP itself.","created_at":"2016-11-14T16:00:17Z","updated_at":"2016-12-09T01:19:54Z","closed_at":"2016-12-09T01:19:54Z","merged_at":null,"merge_commit_sha":"609adc0d6693e3fb9b159ff6ac4530518df4bc77","assignee":null,"assignees":[],"milestone":null,"commits_url":"https://api.github.com/repos/dotnet/roslyn/pulls/15212/commits","review_comments_url":"https://api.github.com/repos/dotnet/roslyn/pulls/15212/comments","review_comment_url":"https://api.github.com/repos/dotnet/roslyn/pulls/comments{/number}","comments_url":"https://api.github.com/repos/dotnet/roslyn/issues/15212/comments","statuses_url":"https://api.github.com/repos/dotnet/roslyn/statuses/ed6b0c586134f760b7cd56e8ee6b4fc8d92e0083","head":{"label":"heejaechang:primaryworkspace","ref":"primaryworkspace","sha":"ed6b0c586134f760b7cd56e8ee6b4fc8d92e0083","user":{"login":"heejaechang","id":1333179,"avatar_url":"https://avatars.githubusercontent.com/u/1333179?v=3","gravatar_id":"","url":"https://api.github.com/users/heejaechang","html_url":"https://github.com/heejaechang","followers_url":"https://api.github.com/users/heejaechang/followers","following_url":"https://api.github.com/users/heejaechang/following{/other_user}","gists_url":"https://api.github.com/users/heejaechang/gists{/gist_id}","starred_url":"https://api.github.com/users/heejaechang/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/heejaechang/subscriptions","organizations_url":"https://api.github.com/users/heejaechang/orgs","repos_url":"https://api.github.com/users/heejaechang/repos","events_url":"https://api.github.com/users/heejaechang/events{/privacy}","received_events_url":"https://api.github.com/users/heejaechang/received_events","type":"User","site_admin":false},"repo":{"id":30170221,"name":"roslyn","full_name":"heejaechang/roslyn","owner":{"login":"heejaechang","id":1333179,"avatar_url":"https://avatars.githubusercontent.com/u/1333179?v=3","gravatar_id":"","url":"https://api.github.com/users/heejaechang","html_url":"https://github.com/heejaechang","followers_url":"https://api.github.com/users/heejaechang/followers","following_url":"https://api.github.com/users/heejaechang/following{/other_user}","gists_url":"https://api.github.com/users/heejaechang/gists{/gist_id}","starred_url":"https://api.github.com/users/heejaechang/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/heejaechang/subscriptions","organizations_url":"https://api.github.com/users/heejaechang/orgs","repos_url":"https://api.github.com/users/heejaechang/repos","events_url":"https://api.github.com/users/heejaechang/events{/privacy}","received_events_url":"https://api.github.com/users/heejaechang/received_events","type":"User","site_admin":false},"private":false,"html_url":"https://github.com/heejaechang/roslyn","description":"The
