Visual Studio error: Package did not load correctly

dnlnln

The following error occurs when loading Visual Studio after installing ReadyRoll:

The 'ReadyRoll.VsPackage.ReadyRollVsPackage, ReadyRollSQLServer, Version=1.13.11.1482' package did not load correctly.

Referring to the ActivityLog.xml reveals the following details about the error:

CreateInstance failed for package [ReadyRoll.VsPackage.ReadyRollVsPackage, ReadyRollSQLServer, Version=1.13.11.1482, Culture=neutral, PublicKeyToken=null]Source: 'mscorlib' Description: Exception has been thrown by the target of an invocation. System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> Microsoft.VisualStudio.Composition.CompositionFailedException: Expected 1 export(s) with contract name "ReadyRollNuGet.VisualStudio.ISolutionManager" but found 0 after applying applicable constraints.

Re-installing/reparing/restarting did not help. Any ideas how to resolve this?

The error occurs as a result of corruption of the extension cache in Visual Studio.

To resolve this, you'll need to delete or rename the ComponentModelCache folder on your machine (per this StackOverflow answer: http://stackoverflow.com/a/17604007/266882)

For Visual Studio 2015, this folder is:

%AppData%\..\Local\Microsoft\VisualStudio\14.0\ComponentModelCache

For example:

C:\Users\johnsmith\AppData\Local\Microsoft\VisualStudio\14.0\ComponentModelCache

(for Visual Studio 2017, replace "14.0" with "15.0")

After removing the folder, restart Visual Studio. It should take a minute or so to rebuild the cache.

If you still get the error, try running the following command:

C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\devenv.exe /setup

Or for Visual Studio 2017:

C:\Program Files (x86)\Microsoft Visual Studio 15.0\Common7\IDE\devenv.exe /setup
