* Major refactor of EditDataMetadata providers * EditMetadataFactory generates "basic" EditTableMetadata objects based entirely on SMO metadata * SmoEditTableMetadata no longer depends on SMO, making it unecessary to mock it * Renamed SmoEditTableMetadata to EditTableMetadata * EditTableMetadata can be extended with DbColumnWrappers * Moving logic for extending a EditColumnMetadata into that class * I *think* this will work for async execution of initialize tasks * Fixing unit tests for new Edit(Table|Column)Metadata classes * Async stuff that works! And passes unit tests * Adding unit tests Adding .idea to gitignore * Adding message to the EditSessionReadyEvent * Fixes from dev merge * Fixing unit tests that Rider didn't catch as failing May have been a bit heavy-handed with the async/await stuff * Couple changes as per PR comments
