The 'CascadePackage' package did not load correctly

I just did an update to VS2019(16.9.0) and now I get this message. (actually on two machines). A restart does not resolve the problem.

What is the CascadePackage? Can I just say No to dialogue box and be OK?

Also...the file it mentions to examine...does not exist anymore, nore the directory it was in. enter image description here

I did find this line in the latest ActivityLog.xml

Solution

  • Seem like this was caused by LiveShare. From Visual Studio Developer Community

    Just search for

    The 'CascadePackage' package did not load correctly

    As for my two issues:

    On one machine...the error went away by starting VisualStudio.

    On another machine I went into Tools->Get Tools and Features...
    Click on Individual components search for Live Share. Uncheck it. Restart VS.

    Go back into Tools->Get Tools and Features...
    Click on Individual components search for Live Share. Check it back.

    More about the ActivityLog...
    Visual Studio uses a /log option on update. This creates the ActivityLog.xml.
    More here /Log (devenv.exe) This is something you can also do yourself.

    The description part of the ActivityLog.xml will list where the problems are. Here is an edited breakdown of the original message in the OP.
