If you have ever been frustrated with the mutli-monitor support in Visual Studio 2008 you’ll be pleased to see what’s coming in VS 2010.
VS 2010 will sport a new WPF IDE. Since the IDE is getting a complete rewrite it allows Microsoft to rethink multi-monitor. Every window in VS will be ‘tear-off’. Drag the properties window to mon2, drag the thread window to mon3. Total freedom and very useful.
