I upgraded to Visual Studio 2015 Update 3 this morning and in my main web solution. Now I get the following warning when I open it. I also get this warning when I open typescript files, and I can no longer comment and uncomment the code through a shortcut or toolbar. I also no longer have IntelliSense, etc.

The XML file says the following:
<entry> <record>851</record> <time>2016/07/04 11:40:28.893</time> <type>Error</type> <source>VisualStudio</source> <description>LegacySitePackage failed for package [Microsoft.VisualStudio.LanguageServices.TypeScript.TypeScriptPackage, Microsoft.VisualStudio.LanguageServices.TypeScript, Version=14.0.0.0, Culture=neutral]Source: 'Microsoft.VisualStudio.LanguageServices.TypeScript' Description: Field not found: 'Microsoft.CodeAnalysis.Shared.Options.ServiceFeatureOnOffOptions.ClosedFileDiagnostic'.

What I tried:
- Recovery Update 3
- Reinstalling typescript and uninstalling the old versions that I installed: https://www.microsoft.com/en-us/download/details.aspx?id=48593
- devenv.exe / updateconfiguration and devenv.exe / clearcache
- Removing% localappdata% \ Microsoft \ VisualStudio \ 14.0 \ ComponentModelCache
- Updating the typescript project version to version 1.8
- Setting the environment variable of the typescript path to 1.8 instead of 1.0
So, now my Visual Studio tells me that I have typescript version 1.8.30 installed.
But in my programs and functions I only have version 1.8.6.0 installed (which is the latest). 
The only thing left to do is reinstall Visual Studio yourself.
Any ideas, suggestions? Thanks!
