Correct comparison of that type must use .Equals as equivalent generic values can be different objects.\r\n\r\nThis surfaced as a bug in determinism.  In the case we had an alias'd using where the target type was generic this Equals method came into play.  Based on whether we got a generic cache hit or not ended up changing the PDB output and as an effect the determinism id of the resulting assembly.\r\n\r\ncloses #7015"},"comment":{"url":"https://api.github.com/repos/dotnet/roslyn/issues/comments/159471972","html_url":"https://github.com/dotnet/roslyn/pull/7019#issuecomment-159471972","issue_url":"https://api.github.com/repos/dotnet/roslyn/issues/7019","id":159471972,"user":{"login":"davkean","id":1103906,"avatar_url":"https://avatars.githubusercontent.com/u/1103906?v=3","gravatar_id":"","url":"https://api.github.com/users/davkean","html_url":"https://github.com/davkean","followers_url":"https://api.github.com/users/davkean/followers","following_url":"https://api.github.com/users/davkean/following{/other_user}","gists_url":"https://api.github.com/users/davkean/gists{/gist_id}","starred_url":"https://api.github.com/users/davkean/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/davkean/subscriptions","organizations_url":"https://api.github.com/users/davkean/orgs","repos_url":"https://api.github.com/users/davkean/repos","events_url":"https://api.github.com/users/davkean/events{/privacy}","received_events_url":"https://api.github.com/users/davkean/received_events","type":"User","site_admin":false},"created_at":"2015-11-25T02:53:52Z","updated_at":"2015-11-25T02:53:52Z","body":"Looks like real failures: \r\n\r\n```\r\nerror CS2001: Source file '/mnt/j/workspace/roslyn_prtest_lin_dbg_unit32/src/Compilers/Core/CodeAnalysisTest/PEWriter/UsedNamespaceOrTypeTests.cs' could not be found.
