Wpf – Visual Studio 2008 Xaml Editor not working / disappeared

Found my own answer:

HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\9.0\Text Editor\XAML\Auto List Members 

Setting to 0x00000000 solves it.

The "Auto List Params" Key seems to have no effect. To top it off, you can still use <Ctrl+Space> to open it up on demand (for setting an attribute you can't think of the name of, etc.)

Pretty nifty!

The only issue that I can see surviving a install/reinstall is a supressed package load failure. Try running the following from a command shell. I'm assuming that Visual Studio is installed at the location "C:\Program Files\Microsoft Visual Studio 9.0"

"c:\program files\microsoft Visual Studio 9.0\common7\ide\devenv.cmd" /ResetSkipPkgs

This will reset all skipped package suppression.

If this works then at some point in time when starting VS or loading a file you were presented with a crytpic dialog that said "Some XML Package failed to load ... " and had a yes/no option. Choosing yes will prevent VS from loading that package in the future and hence preventing the XML editor from loading.

I believe this value is stored within a user registry hive. So it's possible that it would survive uninstall. If this works please let me know as I'd like to file a bug.

Edit I was able to confirm with the owner of this /ResetSkipPkgs feature that this issue will be fixed in the next version of Visual Studio (post VS2008).
