Unable to access T-SQL components & An incompatible DacFx version is installed

After trying to view data from within Visual Studio to error messages appear:

Unable to access T-SQL components

An incompatible DacFx version is installed

Some might have seen this error before and the reason is quite simple. The installed Data-Tier Application Framework version and SQL Server Data Tools do not match the ones required by the database.

Just install the latest version from here:

SSDT: http://msdn.microsoft.com/en-us/data/hh297027

DacFx: http://www.microsoft.com/en-us/download/details.aspx?id=35756

And everything is working fine again.

  1. After two days of messing around and a complete reinstall of my machine this was the answer I was looking for. Thank you!
