So I have my VS 2010 and also just installed VS 2012. After that my main project started showing this error:
“The ‘VSTS for Database Professionals Sql Server Data-tier Application’ package did not load correctly”
And also some other errors about components I have never heard before.
This solution provided by Eric Lee worked for me.
Even though the author intended it for a slightly different set of actions.
Short version (copied from the above website):
- Locate your Visual Studio 2010 installation media.
- In the
\WCU\DAC folder, you’ll find three MSIs:
TSqlLanguageService_enu.msi. Run and install each of them.
- Reapply Visual Studio 2010 SP1.
