Fixed it... Fixed it... Fixed it...
- Opened Programs and Features (run: appwiz.cpl)
- Sorted list of installed apps by: Install Date
- Filtered list by adding "SQL" to the upper right search filter
- List item
I installed VS2012 on 4/1/13, so I went through each listed SQL item in the list, and right click --> Repair
From there I ran VS2012 and opened the target Solution file without issue.
My list:
- Microsoft SQL Server 2012 Data-Tier App Framework
- Microsoft SQL Server Data Tools - enu (11.1.20627.00)
- Microsoft SQL Server 2012 Management Objects (x64)
- Microsoft System CLR Types for SQL Server 2012 (x64)
- Microsoft System CLR Types for SQL Server 2012
- Microsoft SQL Server 2012 Management Objects
- Microsoft SQL Server 2012 Transact-SQL Compiler Service
- Microsoft SQL Server 2012 Command Line Utilities
- Microsoft SQL Server Data Tools Build Utilities - enu (11.1.206...
- Microsoft SQL Server Compact 4.0 SP1 x64 ENU
- Microsoft SQL Server 2012 T-SQL Language Service
- Microsoft SQL Server 2012 Native Client
- Microsoft SQL Server 2012 Data-Tier App Framework
- Microsoft SQL Server 2012 Express LocalDB
- Microsoft SQL Server 2012 Transact-SQL SpriptDom
This worked for me -
In order to fix the issue one needs to clear the Visual Studio cache under:
%LOCALAPPDATA%\Microsoft\VisualStudio\11.0\ComponentModelCache
Thanks go to blog post SetSite failed for package [Microsoft.VisualStudio.Editor.Implementation.EditorPackage].
Usually this can be fixed by clearing the Visual Studio cache under:
Visual Studio 2012: %LOCALAPPDATA%\Microsoft\VisualStudio\11.0\ComponentModelCache
Visual Studio 2013: %LOCALAPPDATA%\Microsoft\VisualStudio\12.0\ComponentModelCache
- Close Visual Studio.
- Open a Developer Command Prompt for Visual Studio 2012 (as administrator).
- Type
devenv /setup
. - Restart Visual Studio.
