Description

Visual Studio hangs with "Waiting for parse to complete..." when opened with the source for source.extension.vsixmanifest visible.

It's actually this issue that has caused me to uninstall Extensibility Tools in the past. It has now happened on multiple extensibility solutions. Sorry I didn't report it earlier. 😊

Steps to recreate

1. Right-click, view source on source.extension.vsixmanifest
2. Close Visual Studio
3. Open Visual Studi

Current behavior

Visual Studio hangs showing "Waiting for parse to complete..." on staus bar

Requires kill devenv process to close.

Expected behavior

Visual Studio opens showing source.extension.vsixmanifest source.
