SQL Server Data-Tier Application Framework (March 2013) Available

What’s new?

This update to the Data-Tier Application Framework (DACFx) addresses several high-priority issues reported by DACFx and SQL Server Data Tools customers via the forum and Connect. The issues addressed include:

  • Database Project in Visual Studio hangs on “Analyzing Database Schema…”
    • This release addresses an issue that can occur when loading or building large Database Projects. In some cases, the operation would never finish.
    • This is a functional fix, not a performance enhancement – even with the fix, the time to complete this operation depends on the size and complexity of your project.  


  • “System.ObjectDisposedException: Store must be open for this operation” failure in DACFx
    • This release addresses an issue that can occur when simultaneously working over multiple Database Projects or DACFx operations. In some case, an error would be encountered and the operation would not complete.


  • “Unexpected failure occurred: hexadecimal value 0xxx, is an invalid character” failure in DACFx
    • This update addresses an issue that can cause the above failure on Export BACPAC and Extract DACPAC operations for certain databases.

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