This could be due to a change in the assemblies shipped with Visual Studio, caused by corrupt installs (or ones with certain features not installed). Needs investigation, but it’s very hard without being able to repro the problem. It basically comes down to having a look in the visual studio folder for this assembly, then finding out from the fusion log why it isn’t loaded.

On my machine (where this works), the assembly is this one:

Microsoft.VisualStudio.LanguageServices.dll	2.10.0.0
c:\program files (x86)\microsoft visual studio\2017\professional\common7\ide\commonextensions\microsoft\managedlanguages\vbcsharp\languageservices\Microsoft.VisualStudio.LanguageServices.dll

The version number matches with this extension in the Extensions and Updates window:

Hi @GrahamTheCoder, release 6.4.0 starts up just fine! Thanks for the quick answer!

The dependencies and startup massively changed in 6.3. I’ll close this until I hear a report from a new version and then try to get an activity log and fusion log.
