Few really useful developer friendly features in VS2010
1. Pin your favorite project so that its always available in the recent projects(even after a year!)
2. Double click a variable to highlight its usage all over the current page (no more find all references). Do a Ctrl+Shift+DownArrow to move to next reference
3. Do a ViewCallHierarchy to find out method dependencies
4. Focus on important code by collapsing rest of the code
Some more useful features like Datatips and export/import breakpoints to improve collaboration with other team members…more on that soon!!
Look forward to VS2010!
