DAC Framework Compatibility
When you attempt an action that uses the DAC Framework, SQL Server Data Tools (SSDT) verifies the version of DACFx on the computer. If SSDT does not work with the installed version of DACFx, the following error displays:
Incompatible versions of SQL Server Data Tools and database runtime components are installed on this computer
You can download a newer version of SSDT from Download and Install SQL Server Data Tools.
