User(s) can reproduce this bug

Resources defined in Application.xaml somehow find their way into Visual Studio application.

Effects can range from funny visual changes to completely breaking VS functionality.

This applies to both RTM and Update1.

This critical bug prevents usage of VS with certain 3rd party controls that happen to have conflicting keys.

Details (expand)

Visual Studio 2012

1. Create WPF app
2. Add to Application.xaml: <LinearGradientBrush x:Key="GlyphBrush" />
3. Rebuild
4. Open MainWindow.xaml
5. Select Window object and show its properties (F4)

Windows 7 SP1

Designer crashes with:

InvalidCastException: Unable to cast object of type 'System.Windows.Media.LinearGradientBrush' to type 'System.Windows.Media.SolidColorBrush'.

No crash, no strange interactions between Visual Studio and application code.

Are you planning to also fix this in Blend bundled with VS2012 ?

Same problem applies to Blend for Visual Studio 2012 (5.2.30810.0).
