We’re aware of issues in Synergy DBL Integration with Visual Studio (SDI) when used with Visual Studio 17.12 that may cause SDI performance issues.

We’re working on creating an SDI update to resolve these issues as quickly as possible. In the meantime, SDI users should either remain on VS 17.11 or roll back to 17.11 if you have already moved to 17.12.
