I open a XAML file. Start editing a control. I want to type in the following simple property setting:

  Background="Transparent"  

That's it. But after typing at most 3 characters, Visual Studio completely locks up never to come back. (I just left it running all weekend and it was still locked up)

If I paste the line into the text editor there is no lockup. But typing it locks up Visual Studio every time.

Here are the things I have tried to fix it. None of them have worked (Note: I always have the XAML designer disabled, even before this happened so I did not need to disable it)

• I've tried individually disabling extensions, particularly Resharper and Visual Assist.

• I have tried manually disabling every single extension that I have installed.

• I've tried disabling all intellisense options that can find in Tools >> Options.

• I've tried deleting the .vs subfolder where my solution file lives

• I've tried deleting the component model cache, both manually from the folder where it lives and using Mads Kristiansen's "Clear MEF Component Cache" extension

• I've tried starting Visual Studio from the command line with the /safemode switch

• I've tried starting Visual Studio from the command line with the /resetsettings switch

• I've tried using the Visual Studio installer to repair the installation

• I was told to "delete the .suo file" but I don't have one because i use the new .SLNX solution file format.

• I've tried (on a suggestion from .AI) to go into the .csproj file and add the following lines (which did not help)

<DisableXamlTypeBackgroundCompilation>true</DisableXamlTypeBackgroundCompilation> <XamlDebuggingInformation>False</XamlDebuggingInformation>

Does anyone have any idea what will fix this?
