This reverts commit 96593d66e3.
* Revert "Switch Tools Service to new SMO and Microsoft.Data.SqlClient driver (#865)"
This reverts commit 9d140b53f3.
* Bump SMO to 160.1910315.0-preview
* switch to ambient props and targets files
* build against Microsoft.Data.SqlClient
* build tests
* fix test bug
* temporarily add SMO nuget to the repo
* update to released Microsoft.Data package
* Ensure connection open for OE queries and fix connection disposal
- Dispose connection in Metadata service, to ensure we cleanly dispose and don't rely on garbage colleciton
- Fixed issue where if the connection was closed, expanding databases in the Server would fail. This is because SMO doesn't always reopen the connection, certainly not for Server level queries. The solution is to always check if open and reopen.
- Added unit tests for this, which required mocking the relevant IsOpen / OpenConnection methods. Refactored SMO wrapper calls into a dedicated class file to handle this
