Automatically update vsixmanifest to reference nested VSIX

[sharwell]

When the Output Window Services extension is installed in a project via NuGet, it could automatically update the source.extension.vsixmanifest file to reference the nested VSIX file.

Open questions:

• What is the syntax for referencing a nested VSIX file in the Version 2 vsixmanifest?

Closed questions:

• When a NuGet package is upgraded to a new version, does uninstall.ps1 from the previous version run followed by install.ps1 from the new version?
  • Answer: Yes, it does.

I tried to use NuGet's XDT support for this, but even the following trivial transformation results in an exception when I try to install the package.

<?xml version="1.0" encoding="utf-8" ?>
<Vsix xmlns="http://schemas.microsoft.com/developer/vsx-schema/2010"
      xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
</Vsix>
