What’s new?

This release of the Data-Tier Application Framework (DACFx) brings fixes for several customer-reported and high-priority issues including:

  • SSDT crashes when opening a table that contains specific computed column definitions from SQL Server Object Explorer
  • Incorrect parsing errors when using system functions (@@) in specific scripts inside SSDT
  • Importing a BACPAC to Windows Azure SQL Database may experience data loss when connection to database is being throttled
  • Exporting a Windows Azure SQL Database to a BACPAC file may experience data loss when connection to database is being throttled

The team thanks you for your feedback in reporting these issues!

With this release, we’ve also made significant improvements in overall operation performance and stability when targeting Windows Azure SQL Database with DACFx.

How can I get it?

You can obtain this new version of DACFx and its dependencies from our Microsoft Download Center page here. This version of DACFx supersedes all previously available versions. This new version of DACFx supports in-place upgrade from previous versions, so it is not required to remove previous DACFx installations before upgrading to this new release.

(Update 11/19) If you are on an x64 machine, you will need to install both the x64 and x86 versions of the MSIs from the DACFx November download page linked above. 


This release of DACFx is fully compatible with the November 2012 release of  SQL Server Data Tools released on 11/7, available here. This release is also compatible with SSMS of SQL Server 2012 and SQL Server 2012 SP1.

If you experience any issues or have any feedback, please let us know via the forum or Connect. We look forward to hearing from you!

  • After upgrading the Data-Tier Application Framework, SQL Server Data Tools upgrade dialog still pops up for me when starting Visual Studio 2012. It claims 11.1.2816.0 version is installer instead of 11.1.2820.0. I checked the c:\Program Files (x86)\Microsoft SQL Server\110\DAC\bin\Microsoft.SqlServer.Dac.dll file and it has 11.1.2820.0 version.

  • Tadeusz,

    We are looking into this issue this morning. Please see this thread for more details - social.msdn.microsoft.com/.../9af0e749-65e2-4fa8-a4ee-d2035260dc7a. I will update that thread if we uncover any new information.



  • Thanks Adam - installling x86 resolved the problem.

  • If i'm on a x64 machine, do I really have to install all 6 .msi files?

  • Hi Adam,

    Can I make a suggestion? When you post these blogs about updates to either DacFX or SSDT that you tell us how to determine what version of those are already installed. Give us screenshots about what we should see *after* the update has been installed.

    The reason I suggest this is that I am currently trying to do an audit of all our developer workstations & servers to determine what version of SSDT, Power Tools & DacFX we are running to make sure we are consistent. I don't actually know how to do that because I do not know how to determine this information.
